Information on radon and reports from the Centre for Radiation, Chemical and Environmental Hazards (CRCE).

Radon is a colourless, odourless radioactive gas. It’s formed by the radioactive decay of small amounts of uranium that occur naturally in all rocks and soils.

The main danger from high radon exposure is the increased risk of lung cancer. For most people, radon is the single largest source of radiation exposure whether they are at home or at work.

Public Health England (PHE) is the UK’s primary expert on radon and radiation protection. PHE provides resources and advice about radon for the public, including individual householders, industry, education and research.

The UKradon website has more information about radon, including:

  • health risks
  • maps of radon-affected areas
  • the radon measurement services that PHE offers

The PHE blog Public health matters includes radon.
