Radon Recommendations for Authorities

National authorities have an important role to play in reducing radon levels.

National authorities should:

  • have a reasonable understanding of indoor radon exposures across the country
  • develop a national radon protection strategy

The national radon protection strategy should be straightforward and realistic, and be considered in conjunction with other public health policies, such as energy saving, non-smoking, and indoor air quality. It should address exposures in new and existing buildings, aiming to reduce:

  • the overall exposure of the general population
  • the highest individual exposures

To help guide action, authorities should set a national reference level for indoor radon levels:

  • ICRP recommends setting a national reference level as low as reasonably achievable in the range of 100–300 Bq/m3.
  • WHO guidance is basically the same: a national reference level of 100 Bq/m3 is recommended, and wherever this is not possible, the chosen level should not exceed 300 Bq/m3.
