As property owners, it is crucial to ensure the safety and health of those living in your properties. One of the lesser-known risks you might face is the exposure to radon, a radioactive gas that can cause lung cancer. The presence of radon is not easily detectable as it is colourless, odourless and tasteless. The key to managing this risk boils down to understanding radon levels, implementing regular tests, and taking protective measures. This article will equip you with the necessary knowledge to determine if your property in the northern UK is at high risk for radon exposure.
Understanding Radon and its Health Implications
Before we delve into how to identify the risk of radon exposure in your property, let’s first understand what radon is and how it can impact health. Radon is a naturally occurring radioactive gas that is released during the decay of uranium found in rocks and soils.

In outdoor areas, radon disperses quickly into the atmosphere and poses little threat. However, when it seeps into confined spaces like buildings or homes, it can accumulate to dangerous levels, increasing the risk of lung cancer, especially for smokers. The World Health Organization asserts that radon is the second leading cause of lung cancer after smoking, contributing to between 3% and 14% of all cases worldwide.
The risk from radon is long-term and depends on the level of radon, how long you are exposed, and whether you are a smoker or not. It is worth noting that children are more susceptible to radon-induced health risks due to their higher respiratory rates and rapidly dividing cells.

Recognising High Radon Areas in the Northern UK
The first step in assessing the risk of radon exposure in your property is to determine if you are located in a high radon area. The UK has a comprehensive radon map that outlines areas with high radon potential.
The northern UK, including areas like Northumberland, North Yorkshire, and East Riding, has been recognised as high radon areas. The Health Protection Agency estimates that in some of these areas, up to 30% of homes are above the UK’s radon action level. Therefore, if your property is located in these regions, it is critical to conduct radon tests frequently.
Performing Radon Tests on Your Property
Testing is the only accurate way to determine the level of radon in your property. You can purchase radon test kits from reliable sources or hire a professional radon tester. The testing process typically involves placing a small measuring device in the lowest occupied area of your property for a specified period, usually three months. The device will then be sent to a laboratory for analysis, and you will receive a report detailing the radon levels in your property.
If the radon level in your property is above the UK’s action level, don’t panic. High radon levels can be managed with radon reduction measures. It’s also crucial to conduct radon tests every few years, as radon levels can fluctuate over time.
Taking Protective Measures Against Radon
While you cannot completely eliminate radon, you can reduce its levels in your home. This involves a range of techniques, such as increasing ventilation, sealing floors and walls, or installing a radon sump system.
Increasing ventilation in your property can help disperse radon, reducing its concentration. You can achieve this by installing exhaust fans, using air conditioning units and opening windows frequently.
Sealing cracks in floors and walls can limit the amount of radon entering your property. A more effective solution, though, is to install a radon sump system. This works by creating a vacuum under the property, which sucks out the radon gas and releases it into the atmosphere.
It’s important to consult with a radon mitigation professional to determine the most suitable solution for your property. They can also provide advice on how to maintain lower radon levels in the long term.
Monitoring and Responding to Radon Levels in Your Property
Having implemented radon protection measures, it is essential to continue monitoring radon levels in your property. Regular testing, especially in high radon areas, will ensure that the measures in place are effective and that radon levels remain low.
If radon levels rise above the action level, it is critical to review and possibly upgrade your protection measures. Consult with a radon professional to understand why the previous measures may not have been effective and to develop a more robust plan.
Remember, radon exposure is a significant but manageable health risk. With the right information, regular testing, and diligent maintenance of protection measures, you can ensure the safety of your property against radon.
Implementing a Radon Mitigation System
Recognising that your property sits in a high radon area or has tested above the UK’s radon action level necessitates action. Radon mitigation systems aim to reduce radon levels, making your property safer. These systems vary, and selecting the right one depends on your property’s unique characteristics.
One common method of radon mitigation is the radon sump system. This involves creating a vacuum under your property, drawing radon gas from the soil and discharging it into the atmosphere, therefore reducing indoor radon levels. Another technique is to seal cracks and gaps in your property’s floors and walls. Sealing these gaps can limit the amount of radon gas seeping in, significantly reducing radon levels inside your property.
Improving ventilation within your property also helps reduce radon levels. You can accomplish this by installing exhaust fans, air conditioners, and by regularly opening windows. These measures help disperse radon gas, minimizing its concentration indoors.
However, these mitigation measures must be professionally installed to ensure their effectiveness. Hence, hiring a certified radon mitigation professional is crucial. They will evaluate your property, recommend the most suitable mitigation system, and install it correctly. Continuous monitoring and maintenance are essential to maintain reduced radon levels, ensuring the system’s long-term effectiveness.
Conclusion: Ensuring Health Safety Against Radon Exposure
Radon gas exposure is a significant, yet often overlooked, health risk, especially in regions like Northumberland, North Yorkshire, and East Riding, which are identified as high radon areas on the UK radon map. Prolonged exposure to high radon levels can lead to lung cancer, emphasizing the importance of managing this risk in your property.
Testing is the most effective way to determine if a property has high radon levels. Regular radon testing, especially in high radon areas, not only helps identify a problem but also verifies the effectiveness of any installed mitigation systems. If testing reveals radon levels above the UK’s action level, it’s time to consider installing a radon mitigation system.
While it’s impossible to eliminate radon entirely, implementing effective radon mitigation measures can significantly reduce radon levels in your property, safeguarding occupants’ health. A certified radon professional can guide you through this process, from testing to installation and ongoing maintenance.
In conclusion, understanding radon and how to manage its risk is critical for property owners. By being proactive about testing, mitigating, and monitoring radon levels, you can ensure a safer and healthier environment for those occupying your property.
