Buying a home involves countless checks and considerations. Buyers look at location, structural conditioning, energy efficiency, roofing and for signs of damp. All of which are important factors when making such a significant investment, though many overlook if the property is affected by radon.

When your solicitor carries out various checks (Searches) they will check to see if the property is in a radon affected area. If the Search shows that the property is in a radon affected area, do not panic!

What is Radon?

Radon is a naturally occurring radioactive gas that can affect properties of all types, ages, locations and uses. The gas is formed when uranium in the soil and rocks beneath us decays. When it permeates the ground into the open air, it is quickly diluted to low concentrations, however if it rises into a building, it can become trapped and build to dangerous concentrations.

Are Certain Areas More Affected?

Some parts of the UK are known to have a higher likelihood of elevated radon levels due to local geology. Buildings with basements are also more susceptible to high levels of radon accumulating, as there is a larger surface area in contact with the soil through which the gas can permeate.

UKHSA advise that any property with a basement, regardless of whether it is located in an ‘affected area’ or not, will have an increased probability of containing high radon. You can check if properties fall within ‘radon affected’ area using the UKHSA maps.

It is important to recognise that the maps are only an indicative guide as to which parts of the country are most likely to be affected by high levels of radon. They are not definitive. Properties in lower risk areas may still be affected by radon.

The maps are not property specific, and they do not indicate how high the radon concentrations area; they are based upon an estimated number of properties with radon concentrations above the ‘action level’ rather than the radon concentrations likely to be found.

How do I Know if There is Radon in a Building?

With radon being odourless, colourless and tasteless, the only way to assess the level of radon is to conduct a test.

Various digital monitors are available; however the most common method of radon testing involves placing special passive detectors in the property for a period of time before returning them to a laboratory for analysis.

Passive radon detectors are small and discreet when in use, and then whole process including analysis is inexpensive.

As radon levels fluctuate according to seasonal and occupations variances, a three-month period is normally recommended to take such inconsistencies into account.

How can High Radon Levels be Reduced?

The good news is that there are several techniques available that can successfully reduce radon concentrations within a building and prevent future intrusion of radon.

As radon enters a building due to the pressure differences between the building and the ground, the main methods of dealing with radon in existing buildings is to alter this pressure ration. This can be done either through the installing of a positive pressure unit, or a retrofit sump system.

For more information on radon, read UKRA’s online guides.

Of course not.

You can’t see it, but you can test for it.

When we think about keeping children safe at home, we naturally focus on the visible dangers. We install stair gates, cover plug sockets, secure cupboards and test spoke alarms, as these are the risks we can identify immediately.

But what about the risks we can’t see?

What is Radon?

Radon is a naturally occurring radioactive gas released from rocks and soil beneath the ground. Outdoors, it disperses harmlessly into the air. Indoors, however, it can become trapped and build up to the elevated levels without anyone realising.

It enters properties through small gaps and openings such as:

· Cracks in the floors and walls

· Gaps around pipes and cables

· Construction joints

· Crawlspaces and basements

Radon is completely invisible and has no smell or immediate symptoms, so many homeowners have no idea it may be present inside their property.

Radon is recognised as one of the leading causes of lung cancer after smoking. The risk increases with long-term exposure, particularly in spaces where people spend many hours each day.

Testing is Simple

Although radon itself is invisible, testing for it is straightforward.

A radon test measures the concentration of gas inside a property over a period of time, helping homeowners understand whether levels are within action limits.

Many people assume their property is safe because neighbouring homes have not reported issues, but radon levels can vary significantly even between houses on the same street.

For most residential properties, testing is considered good practice if the property has been identified as lying in a radon ‘affected area’.

Awareness

One of the biggest challenges surrounding radon in the UK is simply awareness. Many people have heard the word but know very little about what it is, how it enters homes, or why testing matters.

As awareness grows, more families can make informed decisions about indoor air quality and long-term health.

Ultimately, creating a safe home is not only about addressing the dangers we can see, but understanding the ones we cannot.

Small steps today can help provide reassurance and protection for years to come.

Testing for radon gas within a property is the only way to understand if harmful levels of radon are present, though many are left wondering how often a test should be carried out.

Whilst some may think that a single test is enough, radon levels are not fixed. They can fluctuate over time due to environmental conditions and building alterations. Understanding when and how often to test is key to ensuring the occupiers protections.

Why Test More Than Once

A single radon test, especially a short term one, provides a snapshot of conditions at a specific point in time. Changes in season, ventilation, soil condition and alterations to building structure can all contribute to radon level fluctuation.

Relying on a one-time result may create a false sense of security, while performing ongoing tests will help confirm that radon levels remain within acceptable limits.

Testing Frequency

For most residential properties, the following approach is considered good practice if the property has been identified as lying in a radon ‘affected area’.

· Initial Test: As soon as possible, especially if the property has never been tested

· Follow-Up Testing: At least once every 10 years to confirm levels remain stable

· After Installing a Mitigation System: To verify that it is working correctly

· Periodic Re-Testing: When a mitigation system is in place, re-test once every two years

Certain situations call for more regular testing.

Renovations or structural changes such as extensions, installation upgrades, new flooring, or changing in ventilation can all affect how radon enters and behaves within a building. Installing extractor fans or air conditioning units, sealing drafts, or improving air tightness can all alter airflow and pressure, potentially influence radon levels.

If earlier tests showed radon levels approaching recommended limits, it is worth re-testing more frequently.

Testing After Installing a Mitigation System

Testing after installing a radon mitigation system confirms that the system is functioning correctly, radon levels have been reduced effectively, and no additional adjustments are required.

Even after successful installations, periodic re-testing is essential. Systems can become less effective over time due to wear, building changes or environmental factors.

Practical Approach for Property Owners

A simple proactive approach can make a significant difference:

· Test your property if you have not done so before

· Retest periodically rather than relying on a single result

· Test again after any major building changes

· Confirm performance after installing mitigation systems

Treating radon testing as a routine part of property maintenance helps ensure that protection is ongoing. Regular testing provides reassurance, identified potential issues early and ensures that any mitigation measures continue to perform effectively.

By adopting a regular, planned testing approach, homeowners and property managers can take control of radon risk and maintain a healthier indoor environment.

Exposure to radon gas can cause serious health risks, yet misconceptions about it remain widespread all over the world. As radon is invisible, odourless, and not widely talked about, many homeowners rely on assumptions rather than accurate information.

Myth: Radon Only Affects Older Homes

It’s easy to assume that radon is only an issue in older properties with aging foundations, yet in reality, radon can affect any type of building regardless of age.

If the proper measures are not put in place at the time of construction, newer homes are often built with energy efficiency in mind, which can actually help to trap radon indoors more effectively. Without proper ventilation or mitigation systems, radon levels can build up just has easily no matter the age of the property.

Myth: If my Neighbour’s Home is Safe, so is Mine

It is possible for radon levels to vary between neighbouring properties, even on the same street. This is because the movement of the gas depends on ground conditions, airflow, and building-specific factors such as foundation condition and property alterations.

The only safe way to know the level in your property is through testing your own home.

Myth: Once a Mitigation System is Installed, the Problem is Solved Forever

This myth was the main focus of our blog last month. Radon mitigation systems are highly effective, but they’re not a permanent, maintenance free solution. Over time, components can degrade and systems may become less efficient without obvious signs.

Without periodic testing and maintenance, a system may no longer be providing your property with the same level of protection as it once did. Ongoing monitoring is essential to ensure your system continues to perform as intended.

Myth: If you Can’t See or Smell it, it’s Not a Problem

Radon is an odourless, colourless gas. It is impossible to be detected by humans as there is no physical sign that it is present.

This makes in particularly important to test for radon, especially if your property falls into an radon affected area outlined by the UKHSA maps.

Myth: Radon Gas Exposure isn’t a Serious Risk

Radon exposure is sometimes underestimated as the effects of exposure are not immediate. Long-term exposure to elevated radon levels poses a significant health risk as it increases the likelihood of developing lung cancer over time.

The risk is higher with prolonged exposure, which is why unnoticed radon is a serious concern.

More Information

Addressing radon doesn’t have to be a complicated process. Guidance and advice can be found online on the UK Radon Association website:

• General Information
• Information for Employers
• Information for Householders
• Information for Landlord & Tenants
• Information for House Buyers & Sellers
• Information about Radon in Basements

We know that exposure to radon gas, which is found in homes all over the country, accounts for the second greatest number of lung cancer cases in the UK. Fortunately, there are several techniques available that can successfully reduce radon concentration within a building and prevent future intrusion.

These mitigation systems are installed to reduce health risks and create a safer indoor environment. Although, once fitted, it is easy to assume that they will continue working indefinitely without attention.

In reality, the effectiveness of radon mitigation systems depends on basic maintenance and periodic testing to ensure they continue to perform as intended.

Why Maintenance Matters

Changes in airflow, fan performance or structural conditions can affect how well mitigation systems control radon levels. Without maintenance, a shift in performance may go unnoticed.

Maintaining the system ensures it continues to actively reduce radon concentration. The difference between a functional and non-functional system may not be visible, but it is significant.

Real-World Consequences

A widely reported case involving Kingswood School in Bath demonstrates the importance of monitoring and maintenance of mitigation systems.

BBC News reported that the school had previously identified elevated radon levels and installed mitigation measures. However, follow-up monitoring was not consistently maintained thereafter.

It was revealed that five pupils, two employees and their children had been exposed to high levels of radon gas. Kingswood School Trustees Limited pleaded guilty to breaching Section 2(1) and 3(1) of the Health and Safety at Work etc Act 1974 and were fined £50,000.

Issues that Reduce Effectiveness

Over time components of mitigation systems can become less efficient. Seals may degrade, pipework may develop leaks or filters can become clogged and reduce airflow. External changes such as renovations, or landscaping adjustments may also influence the systems performance.

Monitoring & Testing

Radon levels can fluctuate due to seasonal changes or building usage and ventilation, which means periodic measurement provides reassurance that protection is being maintained. Continuous monitoring will help identify if radon levels begin to rise, which can prompt investigation before the situation becomes more serious.

Peace of Mind

Regular maintenance will help build confidence that the systems are working as they should be. Knowing the system is checked and functioning provides reassurance that indoor air quality is actively being managed.

This peace of mind is particularly important in environments where occupants spend significant time, such as homes, workplaces, and community facilities.

A Practical Approach to Maintenance

Treating mitigation systems as an ongoing safeguarding process, rather than a one-time installation, helps ensure they continue to protect occupants for years to come.

The experience at Kingswood School serves as a clear reminder that installation is only the first step. Ongoing monitoring and maintenance are what ensure radon mitigation systems continue to deliver the protection they were designed to provide.

Hybrid working is now a normal work practice, and one that is fairly common across the UK, but with it comes a new set of challenges for health and safety. One often-overlooked risk is radon exposure, a naturally occurring radioactive gas that can accumulate indoors and is the second leading cause of lung cancer after smoking.

Why Radon Matters

Radon is the largest source of radiation for most people in the UK. It’s not often talked about, as outdoors it dissipates harmlessly, but indoors, and especially in basements or poorly ventilated spaces, it can build to dangerous levels.

While most inhaled radon is exhaled, its decay products can lodge in the lungs, emitting radiation that damages cells over time.

Hybrid Working & Home Offices

With more and more employees working from home, often in converted spaces like basements, radon risk assessments are essential. Employers have the same duty of care for home workers as for office-based staff. This includes considering environmental risks alongside stress and ergonomic factors.

HSE Guidance:

The HSE have confirmed that: “Where employees work from home, then employers have a responsibility to risk assess that work activity under The Management of Health and Safety at Work Regulations 1999 and that will include consideration of radon in the home. It is up to the employer if they wish to pay for testing of the home environment.

HSE sought legal advice on the subject of radon exposure to homeworkers and application of IRR17 and, in short, the legal position given was that employers had to consider radon exposure to homeworkers and provide relevant information about the risks and options for checking the radon map and testing etc., but it would not be deemed reasonably practicable for an employer to arrange and pay for radon remediation of an employee’s home. ”

When Should You Test?

• Above Ground: Test if your property is in a radon-affected area (check the UKHSA Radon Map)
• Below Ground: Always test if you have an occupied basement office—regardless of location.

Managing Radon Risk for Hybrid Workers

• Provide information on how to assess the risk
• Encourage staff to measure the radon levels
• Notify HSE if staff are working in elevated radon environments
• Encourage staff to install a mitigation system
• Offer a safe alternative workspace

Actions for Employers

• Provide staff with information and encourage radon testing
• Offer safe alternative workspaces if mitigation isn’t immediately possible
• Include radon in home worker risk assessments

Dear Member,

For those of you who don’t know me or are new to the Association, I’m Dr Maria Dugdale, UKRA’s Chair, and in my day job, Managing Director of Radonova.

Following the success of Radon Awareness Week in November 2025, we’re excited to dive headfirst into the New Year and ramp up our operations in 2026.

We plan on publishing monthly blogs, available to read on our website, and emailed directly to all our members. Alongside these blogs we’ll also be creating quarterly newsletters, exclusively for our members.

UK Radon Association’s management committee is currently busy researching how we can best support wider industries, not just our own. We’re looking to develop online training courses about radon awareness, and the responsibilities wider industries have in protecting themselves and others from the dangers of radon gas exposure.

If you see any other radon related news or updates that you would like to share with us, please contact the admin team (secretary@radonassociation.co.uk) so that they can circulate this through member updates and in upcoming blog posts.

I’d like to thank all of the Association’s Management Committee as well as all of our members for their ongoing support of our activities.

Lastly, please remember that all members are able to update their company information and services list through the UKRA member’s area. If you need support with this, please contact the admin team.

UKRA Chair

The UK Radon Association (UKRA) has written an open letter to the Secretary of State for Health and Social Care, Rt Hon Wes Streeting MP, urging the Government to take decisive action against the deadly but invisible threat of radon gas. Radon is the leading cause of cancer in non-smokers, leading to over 1,100 lung cancer deaths every year in the UK.

The letter, sent to coincide with Radon Awareness Week 2025 (3rd–9th November), challenges the Government to broaden its public health agenda beyond its Tobacco and Vapes Bill to tackle one of the country’s most overlooked causes of cancer.

“If the Government is serious about creating a smoke-free generation, it must also protect children and families from other preventable causes of lung cancer,” said Dr Maria Dugdale, Chair of the UK Radon Association. “Radon exposure is an entirely avoidable risk, yet thousands of people remain unaware they’re being exposed in their own homes, schools, and workplaces.”

In its letter, which has been signed on behalf of all 30 members of the trade association, UKRA has outlined three urgent actions for the Department of Health and Social Care to implement:

1. Launch a nationwide radon communications campaign for schools – ensuring all schools understand and meet their legal duty to assess and manage radon risks. According to anecdotal evidence from the Health and Safety Executive (HSE), as many as two-thirds of schools in radon-affected areas have never been tested, leaving over 100,000 children potentially exposed to high radon levels.
2. Extend awareness efforts to nurseries and early years settings, including privately run institutions, a sector that has been overlooked in previous radon initiatives but where young children spend many hours each week.
3. Distribute radon information through local health services and health visitor teams, to help families understand the risks at home and take preventative action.

“This is a moment for the Government to do what government’s before have failed to do and show real leadership around radon,” Dr Dugdale said. “By taking simple, coordinated action now, we can prevent unnecessary suffering, save lives, and protect future generations.”

Radon is a colourless, odourless radioactive gas caused by the natural radioactive decay of uranium in rocks and soil. It can accumulate to dangerous levels inside buildings, particularly in certain regions of the UK and long-term exposure significantly increases the risk of developing lung cancer. Children may be more vulnerable to radon due to their faster breathing rate and smaller lung size leading to higher doses of radon, with early exposure compounding their lifetime risk.

Radon exposure is responsible for around 3.3% of all lung cancer deaths in the UK, yet awareness of the gas remains strikingly low. Unlike smoking, radon is not a lifestyle choice: anyone can be at risk depending on where they live, work, or go to school.

The UKRA says this year’s Radon Awareness Week (3rd–9th November), themed “Invisible Gas, Visible Risk”, is a chance to raise awareness around the risks associated with radon and to educate the public around the simple, effective steps they can take to reduce exposure and prevent avoidable deaths, in homes, schools and workplaces.

UK Radon Awareness Week 2024 Spotlights Key Steps You Might Be Overlooking for a Healthier Home

UK Radon Awareness Week celebrates its 10th anniversary in 2024. Taking place from 4-10 November, the campaign aims to raise awareness of the silent health risk that affects homes, schools and businesses across the UK: radon gas. This year, the campaign is emphasising that radon testing is a simple yet crucial step to ensure a healthy home environment.

What is radon and why does it matter?

Radon is a naturally-occurring radioactive gas, produced by the breakdown of uranium in the earth’s, rock, soil and water. It is colourless, odourless and tasteless and when it enters buildings from the ground, it can accumulate to harmful levels. Long-term exposure to high radon levels is the second leading cause of lung cancer in the UK after smoking and is responsible for over 1,100 deaths from this disease each year.

The overlooked risk

“Nowadays, people are diligent about installing smoke alarms and carbon monoxide detectors in their homes because they recognise the immediate dangers that these devices can protect their families from,” says Dr Maria Dugdale, Chair of the UK Radon Association. She continues, “Similarly, we are all well-versed in needing to open windows when we’re decorating or using strong cleaning chemicals to avoid inhaling fumes. Yet many don’t consider the risks posed by radon. Whilst it’s a less obvious risk and requires some research to establish whether it could affect your home, addressing it is just as crucial for maintaining a safe and healthy living environment.”

Understanding the risk

Radon levels vary across the UK and are largely driven by the differing geologies that our homes are built upon. A simple check of the indicative radon map at https://www.ukradon.org/information/ukmaps will provide the estimated risk in your local area. If the risk of high radon levels being present is greater than 1 in 100, the area is designated as a ‘radon affected area’ and the UK Health Security Agency recommends that testing is carried out in homes to measure the radon concentration. Home testing is a simple process, for which kits are widely available from validated laboratories online or from the UK Health Security Agency. If high levels are detected, proven methods exist to reduce indoor radon concentrations and lower exposure.  Dr Dugdale comments, “Radon testing is easy and affordable, and it could make a huge difference.”

About the UK Radon Association

The UK Radon Association is a not-for-profit, professional organisation of members who are dedicated to the highest standard of excellence and ethical performance of radon measurement, radon mitigation and transfer of radon information for the benefit of members, consumers and the wider public.

We are celebrating 10 years of UK Radon Association!

Throughout our 10 years as an association, we have worked hard to raise awareness of the dangers of radon gas and provide support and information to our members and the general public. UKRA members are made up of companies who are dedicated to the highest standard of excellence and ethical performance of radon measurement and mitigation.

UKRA started in 2013 with only 5 members, all of whom wanted to create an active industry association. Through the growth of the industry and development of the association we now have 27 trusted members working alongside us. A huge thank you to all of our members, both old and new, for their continued support over the years.

2016 saw the launch of our bi-annual Radon Symposium, inviting industry members to learn about the latest radon research projects, updates in policy and developments in radon testing and mitigation techniques. We’ve now held five successful Symposiums, including a virtual event in 2021 at the height of the Covid-19 pandemic. We have welcomed speakers and delegates from across the world to our Symposiums, and look forward to our largest event yet, planned for 2025.

In addition to our Symposiums, in 2015 UKRA founded the UK Radon Awareness Week campaign in effort to spread awareness of the dangers of radon gas to the public. The annual campaign occurs in November to coincide with the international Lung Cancer Awareness Month and European Radon Day (7^th November), and each year UKRA releases easy-to-understand material in a variety of formats. Animated videos, press releases, infographics, radio segments and live on-street interactions are just some of the ways we’ve been reaching people with information on radon.

A recent survey we conducted as a part of Radon Awareness Week 2023 however showed that just 10% of the people we asked know what radon is or where it comes from, and almost 70% of people thought more could be done to raise awareness, meaning we still have plenty to do as an industry*.

Our most recent campaign has been picked up nationally by MSN, “Silent killer in our homes cause 1,000 lung cancer deaths a year”,  advising the public about the risks of radon and noting the definite cause for concern.

During 2023 many of our members have seen a significant increase in radon testing enquiries, and this is in no small part due to enforcement action by HSE on employers who are not compliant with radon risk assessment legislation.  In July, HSE prosecuted an employer for failing to protect staff from radon gas, and the regulator has issued numerous other Notices of Contravention to employers across the country.

UKRA was also a founder member of COIRA, the Coalition of International Radon Associations which brings together the expertise from trade organisations across the world, so that we can learn from others and share best practice for mutual benefit.

We look forward to UKRA going from strength to strength as the industry grows, and welcome applications for membership from any organisations involved in the field.

For more information on radon gas aimed at employers, householder, landlords & tenants and house buyers & sellers please explore our Guide to Radon.

*Independent survey of 3532 people conducted in October 2023.

During UK Radon Awareness Week 2023, the UK Radon Association will be working hard to ensure members of the public have a greater awareness and understanding of the issue.

Dr Maria Dugdale, Chair of UK Radon Association said, “Increasing awareness of radon is vital if the number of deaths from radon-related lung cancer is to be reduced. These deaths are largely avoidable, but many homeowners, landlords and employers still aren’t aware of the need to test their properties.”

She continued, “Over the past twelve months, there have been some significant milestones in the radon field; the first new indicative map for 15 years for the whole United Kingdom was published by UKHSA and, in a landmark ruling, the first employer in the UK was prosecuted by the Health & Safety Executive for failing to protect employees and other building users from exposure to high levels of radon. We will be highlighting the impact that these events have had, and encouraging all to take action on radon throughout the week.”

Radon Awareness Week runs from  6th – 12th November 2023. Find out more about the campaign and download resources at www.radonweek.co.uk. Join in the discussion online using #radonaware and follow us on Linkedin and Twitter for updates throughout the week.

BBC Radio Bristol approached the UK Radon Association following the news that Kingswood School in Bath had been found guilty of failing to protect staff and pupils from the dangers of radon in an HSE investigation.

Dr Maria Dugdale, Chair of UK Radon Association discussed the case with BBC journalist Steve Yabsley and provided insight into the requirement for employers to carry out a radon risk assessment, as well as the long term dangers of radon exposure.

Maria signposted listeners to where to find further information on radon, including the interactive maps at www.ukradon.org and the UK Radon Association website which includes a directory of members providing radon testing, mitigation and consultancy services.

You can listen to the whole interview below.

The Health & Safety Executive have successfully prosecuted a private boarding school for failing to protect staff and pupils from exposure to radon, the naturally occurring radioactive gas that can lead to lung cancer.

An HSE investigation found that Kingswood School in Bath, Somerset were aware they had an issue with high levels of radon in some of their buildings in 2007 and carried out some remedial works at that stage to reduce concentrations. Between 2010 and 2018 however the school carried out no further monitoring or checks on the control measures, and this only came to light following intervention from HSE in 2018.

HSE reports that five pupils at the school were exposed to levels of radon almost 8 times the legal limit and two other children, who were not pupils at the school, were exposed to levels of radon almost 14 times the legal limit. Two employees at the school were also exposed to high levels of radon during the period in question.

The school has been fined £50,000 and was ordered to pay £19,222 costs. This landmark case was the first time an employer has been prosecuted for radon-related infringements in the UK.

HSE Principal Specialist Inspector (Radiation) Stewart Robertson, said “We will not hesitate to take action against companies, including schools, who do not do all that they should to keep people safe. Every workplace needs to consider radon as a risk to its employees and others”.

The UK Radon Association (UKRA) welcomes this move and hopes that the case will lead to an improved awareness of radon and the need to properly assess the risks.

Dr. Maria Dugdale, the Chair of UKRA, expressed deep concern over the historic absence of essential processes to safeguard the health of both staff and children at this school, but added that the school had clearly made significant effort to rectify this in recent years. She commented, “We believe that this situation may be replicated up and down the country, not only in schools but across all industries as many employers remain unaware of their responsibilities regarding radon. Radon causes over 1100 deaths from lung cancer each year in the UK yet these are avoidable.”

Dr Dugdale continued, “As an industry, we remain committed to promoting awareness of radon and our members provide reliable testing services and effective mitigation systems to minimise the risks from radon. This unfortunate event serves as a stark reminder of the importance of taking proactive steps against radon and the necessity for collaboration between employers and radon professionals to maintain safe indoor environments for all occupants, especially children.”

The Health & Safety Executive have increased their activity of carrying out workplace inspections relating to radon gas over the past 18 months. Radon is a naturally occurring radioactive gas, which contributes to over 1100 lung cancer related deaths each year in the UK alone.

These inspections have become particularly relevant throughout the education sector. HSE inspectors have written to almost 100 schools in Bath & North-East Somerset to request a copy of their radon risk assessment and test results. Many schools, that had not previously carried out radon testing, have had to undertake the required assessments, and in some cases, have found an elevated concentration of radon gas.

Under the Health and Safety at Work Act 1974 employers must, so far as is reasonably practicable, ensure the health and safety of employees and others who have access to their work environment. Employers are legally required to carry out risk assessments. This should identify all hazards that could be posed to staff, students, and visitors, and should therefore consider radon.

In certain situations, the risk assessment must include radon testing, specifically if the site is located within a designated radon ‘affected area’, or if the site contains a basement or below-groundwork area (that is occupied for 1-hour per week or more).

Several improvement notices have been issued to employers across the UK, in various sectors and industries, where the required radon testing has not been carried out, or mitigation systems have not been properly maintained. Those employers have been informed by HSE that they must complete the required testing or bring systems up to the required standard before the set deadline, or they may face further action.

For example, companies across the UK have been issued notices by HSE for failing to:

• “Review the preventative and protective measures associated with the adequate control of risks associated with the presence of radon gas.”
• “Make and give effect to appropriate arrangements for the effective organisation, control and review of preventative and protective measures required to ensure compliance with the Ionising Radiations Regulations 2017.”

The Ionising Radiations Regulations 2017 (IRR17) are relevant when a test finds radon level in any part of a workplace exceeding the action level of 300 Bq/m³ (Becquerels per cubic metre of air). If this level of radon is found, in accordance with IRR17, employers will be required to take advice from a Radiation Protection Advisor, who may advise that the employer must restrict access to certain parts of the building, display warning signs, or even close the building.

Where remediation is necessary, the cost will depend upon the size and design of the building, as well as the level of radon found. However, the required remediation work is often inexpensive.

Improvement notices issued by HSE are a matter of public record and can be found online. It is in the interest of all employers to ensure that they have completed the necessary risk assessments to avoid any potential negative press.

A number of UKRA members provide radon testing services, radiation protection advice, mitigation design and installation and risk assessment consultancy. They can assist employers to achieve compliance with this legislation. To search UKRA’s list of members please visit our page here.

The UK Health Security Agency (UKHSA) and BGS have provided an updated radon potential map of Great Britain.

Radon is a colourless and odourless gas that is attributed to 1,100 lung cancer deaths per year in the UK – a risk that is highest among smokers and ex-smokers.

The new map provides an authoritative analysis of the likelihood of a building being in a Radon Affect Area, an area where it is estimated that more than 1% of the properties contain high radon levels.

The interactive map, which has taken years of analysis and research to put together, is available HERE. Individuals and employers are being urged to check the new map to see if their property falls under a Radon Affected Area.

It is advised to have your home tested for radon gas if you live or work in an affected area. Properties situated here are more likely to contain high levels of radon due to the underlying geology and varying amounts of uranium present.

The majority of buildings in Great Britain remain outside of Radon Affected Areas, so the overall number of buildings with high radon levels has stayed the same. The new map has refined our knowledge of areas where high radon levels are likely to occur.

The risk of developing lung cancer from exposure to radon remains low, as the map shows that radon levels have not increased in the UK.

Tracy Gooding, principal radiation protection scientist at UKHSA:

“While the vast majority of buildings remain outside Radon Affected Areas, if the property you own is in an affected area, it is important that you arrange for a test.

“If you live in private or social rented accommodation, speak to your landlord, who should organise a test for you to carry out.

“Employers can use this map to help undertake a suitable and sufficient risk assessment and take appropriate action where necessary.

“The updated map provides information that allows property owners, landlords and employers to make informed decisions on the benefits of undertaking radon measurements and potential remediation work.”

Russell Lawley, BGS Principal Geologist:

“Radon occurs in all rocks and soils. Using a revised statistical approach to our mapping of geology across Great Britain has enabled us to model where this geohazard is more likely to be present in buildings.

“This map is a significant update to the previously published version and will help to raise awareness about this geohazard.”

The objective of the new map is to allow local councils, national and regional governments, social and private landlord, private homeowners and employers to assess the radon risk in their properties.

The map will also provide a basis for building regulations where mitigating measures should be put in place for new builds.

UK Radon Association members offer testing services as well as mitigation and surveying. If you live in a Radon Affected Area, please visit our member page to find a supplier near you.

Martin Humphrey Freeman, 31/01/1948 – 08/11/2022.

Martin Freeman, founder and former Chairman of the UK Radon Association sadly passed away on 8^th November 2022 after a long illness.

Martin was the instigator and driving force behind the UK Radon Association’s creation in 2013. He served as Chairman until 2016. He was also a founding member of the European Radon Association (ERA) and sat on its Executive Committee from 2013 – 2018. In 2015 he initiated the Coalition of International Radon Associations (COIRA), bringing together the leaders of the UK, European, American and Canadian radon associations to share knowledge and work together on important cross-border research. He was the Chair for the first two years.

Martin had been involved in the field of radon since 1988. Having been engaged in specialist building preservation services, hygiene and public health services since 1970, in the late 80’s Martin started to receive enquiries regarding radon. For 20 years, he provided ad hoc advice and remedial services to clients in the UK whilst the market was in its infancy.

Following a major heart attack in 2009, when Martin was Managing Director of a national preservation company, Martin made the decision to reassess his work/life balance and focus on the things that mattered most to him for the remainder of his working life.

Martin had a personal interest in the field of radon. In his own words, “2009 also brought the upsetting diagnosis that my eldest sister, Alethea, had lung cancer. Due to lifelong ill-health she spent more time than most at home and, in particular, downstairs in her living room. I had previously tested her house for radon and found the level to be 135 Bq/m3 within the living room, well below the prevailing UK Action Level of 200 Bq/m3. Alethea died from lung cancer in 2011. As to cause, her consultant oncologist agreed that, as a non-smoker who had never been around second-hand smoke, long term radon exposure to a level of 135 Bq/m3 was the likeliest identifiable suspect. Alethea’s death galvanised and energised me to devote my working time to increasing awareness and action against radon. In 2011, I founded propertECO to fulfil that objective along with a colleague from a previous post, Rebecca Coates.”

propertECO quickly became recognised as a leading centre of expertise in the UK, and grew a national client base of everything from private householders to multinational corporations.

Martin retired in 2019 but continued to offer consultancy services to propertECO and independently, and to participate vociferously in national and international policy consultations on radon.

Martin loved to travel and was a popular face at radon conferences across Europe and North America. His sense of humour has been remembered by many over the past few weeks.

UKRA sends condolences to Martin’s family, friends and colleagues. His funeral will be held on Friday 2^nd December in Sherborne, Dorset; anyone who would like details of this is welcome to contact Rebecca on rebecca.coates@properteco.co.uk.

Exposure to radon gas is a leading cause of lung cancer in non-smokers and is responsible for over 1100 deaths in the UK every year. High levels of radon can be found in buildings of any type, size or location with occupants unaware of the potential danger unless a specific test has been carried out.

During UK Radon Awareness Week 2022, the UK Radon Association’s Give Me 5 campaign will bring you 5 important facts about radon for 5 sectors, over 5 days.

Dr Maria Dugdale, Chair of UK Radon Association said, “Increasing awareness of radon is vital if the number of deaths from radon-related lung cancer is to be reduced. These deaths are largely avoidable, but many homeowners, landlords and employers still aren’t aware of the need to test their properties.” She continued, “The Give Me 5 campaign attempts to cut through the often confusing and technical language and bring five key messages to stakeholders in an easy-to-understand format.”

From Monday to Friday during Radon Awareness Week, the campaign will be targeting the information at different groups: families, employers, healthcare providers, school leaders and landlords.

In private housing, there is no obligation to test for radon however it is becoming increasingly requested by prospective purchasers when a property comes onto the market. Landlords have a responsibility under the Housing Act 2004 and the Homes (Fitness for Human Habitation) Act 2018 to assess the risk of radon in each of their tenanted properties. Under the Management of Health and Safety at Work Regulations 1999, all employers must assess health and safety risks, and this includes radon. For both landlords and employers, if the property is located within a designated radon ‘affected area’, radon testing must be carried out to measure the hazard and complete the risk assessment.

Dr Dugdale continued, “For the first time we are including a targeted message for healthcare providers, calling on them to draw patients’ attention to radon and the impact it may be having on their health. If caught early, lung cancer can be treated much more effectively yet there is still a common misconception that it is only a smoker’s disease. If more people realised that being exposed to high levels of radon in their homes or workplaces could lead to lung cancer, whether you are a smoker or not, those with possible symptoms would be less likely to brush them off and seek medical advice sooner.” She continued, “We are also targeting schools as this is a sector that the Health & Safety Executive (HSE) have been particularly active in assessing compliance in over the past 12 months. Many schools have been, contacted by an Inspector requesting to see their radon risk assessment, and if this cannot be produced have been given a deadline by which to provide it.”

Give Me 5 infographics for each of the five stakeholder sectors can be downloaded from the Radon Awareness Week microsite Resources page, and will be shared throughout the week on social media using #GiveMe5 and #radonaware.

At the UK Radon Association’s recent AGM, Lynn Cooper stepped down as Chair after a term of two years and Rebecca Coates was elected to replace her by the Association’s members.

Rebecca, who is also Head of Radon Projects at propertECO was a founding member of the Association in 2014 and has sat on the Board since then, serving as Secretary for the initial four years. She has been a driving force behind the annual Radon Awareness Week campaigns and is passionate about increasing public awareness and understanding of radon gas.

Rebecca said, “I am looking forward to building on the excellent work that has been carried out by the Association over the past few years under the leadership of our outgoing Chair, Lynn Cooper. Many thanks to Lynn for giving her time to help UKRA grow, both in membership numbers and profile. Along with the Vice Chair, Aaron Davidson and Secretary Charlotte Holmes, I will be working hard over the coming year to ensure UKRA provides essential information on radon to the general public, property professionals and the medical community.”

“Following on from the well attended UK Radon Symposium in 2019, we will be holding another Symposium in summer 2021 and will announce further details in due course.

2019 also saw our most successful UK Radon Awareness Week yet, with the issue being discussed live on BBC Radio 2’s Jeremy Vine Show with campaign ambassador, Martin Roberts. This year’s Awareness Week will take place from Monday 2nd November and we will be encouraging all UKRA members to join us in spreading the message that radon exposure is the second leading cause of lung cancer.”

Radon Awareness Week has been a huge success this year, with so much coverage that we actually caused the PHE radon map website to crash due to the increased traffic. Our own website also achieved unprecedented hits, demonstrating the number of people we reached and encouraged to act with our message. Our campaign Ambassador Martin Roberts was interviewed on Radio 2’s Jeremy Vine show, and UK Radon Association board member Rebecca Coates appeared on BBC Radio Cumbria and BBC Radio Stoke, as well as presenting at PHE’s Radon Forum in Chilton.

It was also great to see so many of our members participating by sharing numerous blogs, infographics and posts on LinkedIn and Twitter.

The focus of this year’s campaign was research published earlier this year which found that indoor radon levels are increasing due to the changes we are making to our buildings for energy efficiency purposes. This in turn will lead to an increase in the number of lung cancer deaths attributable to radon exposure.

We hope that by raising awareness we can help reduce the number of unnecessary deaths due to radon related lung cancer.

On behalf of the UK Radon Association I would like to thank all those who have supported the campaign.

The UK Radon Association board meets in a couple of weeks and I’m looking forward to discussing how we will build on this success in 2020 and spread awareness of this important issue even further.

If you missed Martin Roberts discussing radon on the Jeremy Vine Show on Tuesday don’t worry you can listen here for the next 28 days!

UK Radon Awareness Week 2019 begins today, 4th November.

Research published earlier this year has found that indoor radon levels are increasing due to the changes we are making to our buildings for energy efficiency purposes. This in turn will lead to an increase in the number of lung cancer deaths attributable to radon exposure.

The campaign is being backed by TV & Radio property expert, Martin Roberts, who says “The lack of awareness about radon and its health dangers is shocking – and it’s something that could be in any of our homes.” You can hear more from Martin on Tuesday 5th November when he’ll be appearing on BBC Radio 2’s The Jeremy Vine Show at around 1pm.

UKRA is delighted to welcome back Lynn Cooper of Studsvik Ltd as Chair for a second year. This year she will be assisted by co-Vice Chairs Aaron Davidson of BCS Preservation and Darren Turner of A1 Radon and Secretary Elizabeth Howett also from Studsvik Ltd.

At the recent AGM, new Officers for the UK Radon Association were elected. We are delighted to announce that Lynn Cooper (Principal Waste Management Consultant and RPA at Studsvik) has been elected as the new Chair of UKRA.

Lynn said, “I would like to thank the out-going Chairman and Secretary, Martin and Rebecca, for all their hard work at UKRA over the past few years. Their dedication has made UKRA what it is today, and I hope I can continue their work.

The recent Radon Symposium was a great success, and it was excellent to see so many people attending and presenting from abroad as well as the UK. This is testament to the strong connections that UKRA has developed with local and international partners. I hope that during my tenure we can build upon and develop these relationships and continue to raise awareness of radon in the UK.

I look forward to working with the new Vice Chair, Darren Turner, our new Secretary, Victoria Lilley, and all of the Board and members as we continue UKRA’s mission as the professional body for all those involved in radon testing, radon remediation and radon protection across the UK.”

The Association is honoured to have The Right Worshipful The Mayor of Bath (Councillor William Sandry) to welcome delegates to the UK’s first Radon Symposium.  A number of speakers from the UK, North America and Europe are giving presentations aimed at bringing professionals from a range of radon-related fields together.  The Symposium promises to be an excellent opportunity to learn more about the latest developments in the health effects radon; to hear of the latest legislation and guidance covering contractors in the field of radon mitigation; and how others in the international arena are dealing with the health and practical issues surrounding elevated levels of radon in homes and workplaces.
