BGS radon Web service

This Web service provides the Indicative Atlas of Radon Potential for Great Britain dataset. Every building contains radon (Rn) but the levels are usually low. The chances of a higher level depend on the type of ground. The UK Health Security Agency (UKHSA) and the BGS have published a map showing where high levels are more likely. The darker the colour, the greater the chance of a higher level of radon. The chance is less than one home in a hundred in the white areas and greater than one in three in the darkest areas.
