Radon Standards



Radon Standards have been developed by the International Atomic Energy Agency (IAEA), World Health Organization (WHO) and individual countries.  In Canada, the Radon Action Level has been set by Health Canada and guidelines for radon measurement and mitigation have been developed.


For information on the World Health Organization, see the WHO Handbook on Radon.

For information on the IAEA Standards, see their Fact Sheet for Decision Makers

IAEA Safety Standards on Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards

- this includes Public Exposure due to radon and Exposure in Workplaces


Below are the Radon Action Levels of various organizations:

Organization Becquerel per cubic meter Picocuries per liter
World Health Organization 100 Bq/m³ 2.7 pCi/L
Environmental Protection Agency (USA) 150 Bq/m³ 4.0 pCi/L
Health Canada 200 Bq/m³ 5.4 pCi/L
