Radon is a colourless, odourless, radioactive gas. It is formed where uranium and radium are present and can move through cracks and fissures into the subsoil, and so into the atmosphere or into spaces under and in dwellings. Where radon occurs in high concentrations it can pose a risk to health. This publication contains detailed maps of designated radon-affected areas in Scotland and guidance on protective measures.
