Where radon occurs
Radon is a naturally-occurring radioactive gas produced by uranium decaying underground. It seeps into buildings through floors, walls in contact with soil, and through water or gas supplies. When inhaled, radon atoms decaying in our lungs can cause damage to cells and cause lung cancer.
It’s associated with geological types like granite and shale, and the probability of finding high radon levels has been mapped for the UK in the ‘Indicative Radon Atlas.’ Although detailed, it only gives an indication – you have to test to be sure.
