What is Radon Gas?
Radon is a natural radioactive gas that is formed from the decay of uranium in soil, rock, and water. It is colorless, odorless, and tasteless, making it difficult to detect without specialized equipment. Radon gas can enter buildings through cracks in the foundation or walls, and can accumulate to dangerous levels.
Why is Radon Gas Dangerous?
Radon gas is the second leading cause of lung cancer after smoking, and is responsible for around 21,000 deaths each year in the UK. Exposure to high levels of radon gas over a long period of time can increase the risk of developing lung cancer, especially for smokers or those with a history of lung cancer in their family.
Radon Gas Map UK
The UK has a high incidence of radon gas, with around 3% of homes having levels above the recommended action level of 200 Bq/m3. To help homeowners identify whether their property is at risk, Public Health England has created a radon gas map of the UK. The map shows the estimated percentage of homes in each area that are likely to have high levels of radon gas.
How to Use the Radon Gas Map
To use the radon gas map, simply enter your postcode or local area into the search bar. The map will then display a color-coded risk level for your area, ranging from low to high. If your area is identified as high risk, it is recommended that you have your home tested for radon gas.
Testing for Radon Gas
There are two types of radon gas tests available: short-term and long-term. Short-term tests last for around three months and provide an indication of radon levels over a short period of time. Long-term tests last for over 12 months and provide a more accurate picture of radon levels over a longer period.
Radon Gas Mitigation
If your home is found to have high levels of radon gas, there are several ways to reduce the levels. The most common method is to install a radon sump and fan system, which draws the gas out from under the building and vents it outside. Other methods include sealing cracks and installing positive pressure ventilation systems.
Radon Gas and Property Values
If you are buying or selling a property, it is important to consider the potential presence of radon gas. A high level of radon gas can affect the value of a property, and may require costly remediation work. It is therefore recommended that radon gas testing is carried out as part of the property survey.
Radon Gas and Landlords
Landlords are responsible for ensuring that their properties are safe for tenants to live in. This includes ensuring that the property is free from radon gas. If your property is identified as high risk, it is recommended that you have it tested and take appropriate action to reduce the levels.
Conclusion
Radon gas is a silent killer that can have serious health implications. The radon gas map of the UK provides a useful tool for homeowners to identify whether their property is at risk, and take appropriate action. Regular testing and mitigation measures can help to reduce the risk of exposure to radon gas, and ensure that homes are safe for occupants.
