- The action level endorsed by Public Health England (PHE) is 200 becquerels per cubic metre (Bq-m³), the target level is 100 Bq-m³. PHE recommends that radon levels are to be reduced to the target level or lower.

Remediate within 1 year: Results greater than 600 Bq/m 3, Health Canada recommends taking steps to reduce the level within 1 year. While the health risk from radon exposure below the Canadian Guideline is small, there is no safe level of radon.
The Canadian guideline for radon is 200 becquerels per cubic metre (Bq/m³). Health Canada collaborated with the Federal Provincial Territorial Radiation Protection Committee (FPTRPC) to review the health risk from exposure to radon.
Radon is measured in becquerels per cubic metre (Bq/m3). If your home’s radon level is less than 200 Bq/m3, Health Canada radon guidelines say that no action is required. However, even low levels of radon can be harmful.
Jan 1, 2016 · Radon in air is measured in Becquerels per cubic meter (Bq/m 3 ), a measure of radioactive decay per second. Indoors, radon can be measured using both long-term (3 months to a year) and short-term (2 to 7 days) tests.
metre, 1 Bq = 1 radioactive disintegration per second. For example, at a radon level of 200 becquerels per cubic metre (Bq/m3) a smoker with 70 years of exposure, has a 17% risk of developing lung cancer compared to 2% for a non-smoker. In comparison, at a radon level of 800 Bq/m3 the risk for a smoker increases to 30% and 5 % for a non-smoker.
Oct 9, 2023 · Depending on the country, acceptable radon levels vary. A generally accepted action for the level of radon in the air, established by the World Health Organization, is 100 Bq/m3, or 2.7 pCi/L. Homes or structures measuring high radon levels are advised to take remedial action to lower radon levels.
How to Interpret Radon Test Results. The Canadian guideline for radon in indoor air is 200 Bq/m 3. If you’ve tested your home, and the radon concentration is above the Canadian guideline of 200 Bq/m 3, Health Canada recommends that you take action to lower the concentrations.
