Radon is a radioactive gas, we can't see, smell or taste it: you need special equipment to detect it. It comes from the rocks and soil found everywhere in the UK. The radon level in the air we breathe outside is very low but can be higher inside buildings.
Radon is everywhere but some parts of the country are more likely to have high levels in buildings than others. We have worked with the British Geological Survey to produce a data set and maps of the radon prone areas.
High levels of radon can cause lung cancer, particularly for smokers and ex-smokers. Radon produces tiny radioactive particles in the air we breathe. Radiation from these particles damages our lung tissue, and over a long period may cause lung cancer. The higher the level and the longer the period of exposure, the greater the risk will be.
Buildings naturally draw air in from the ground through the cracks and gaps in the floors, and this air will contain radon. Indoor radon often varies from building to building within the same area. The issue of radon comes up when buying and selling properties.
