Radon occurs in small quantities throughout Jersey. It is a natural radioactive gas, colourless and odourless. Radon is a health concern because it can move through the subsoil and into buildings.
Exposure to higher levels of radon for a long time may increase your risk of developing lung cancer. The risk is further increased if you, or someone in your home, smokes indoors.
Advice and testing for radon
If your household or workplace has a ground floor level we recommend you test for radon.
A low cost radon measurement pack can be ordered on the UKradon website or by phoning 01235 822622.
UKradon will provide advice with your results. If the result is high you will also receive guidance on the most suitable remedial method for you. Environmental Health can help you interpret the results.
If you rent, or have concerns about radon levels in your workplace, your landlord or employer can order the pack.
Please note that the interactive map used on the UKradon website doesn't include information about Jersey.
