Radon

Radon is a colourless, odourless radioactive gas formed by the radioactive decay of small amounts of uranium that occur naturally in rocks and soils.

Many buildings contain radon but the levels are usually low and the risk to health is small. 

How can I check if I am at risk?

The darker areas on the UKradon map show where the levels are more likely to be higher. Not all buildings, even in the darkest areas, have high levels but you can order a Radon risk report to measure the level of radon gas in your home. The test is safe, simple to use and the results are treated confidentially. 

What to do if your home has high levels of radon

The Health Protection Agency (HPA) has advised that indoor radon above the level of 200 becquerels per cubic metre (Bq m-3) should be reduced.
If you measure higher levels of radon in your home, then you should take action to reduce these levels, sometimes this could involve sealing around loft-hatches or large openings in floors and extra ventilation for the living space.
