All about radon
Radon is a radioactive gas that is colourless and odourless. It comes naturally from the soil because it is formed from the radium present in the rocks of the subsoil. Radium and radon are both included in the radioactive decay chain of uranium.
Radon in indoor air is a major public health issue in many countries including the UK. However, it is often erroneously referred to as “Cornwall-only” issue, and is not high on the agenda of the UK media. Therefore people are often unaware of the health risks that prolonged exposure to radon can lead to, and although regulations exist to test for radon in schools and workplaces, measuring radon in homes is not mandatory.
