When you get your radon test report

Look for your radon level in order to make a decision of what you should do next. The radon level will be reported in Bq/m³. This is a measurement of radioactivity because radon is a radioactive gas.

If your radon level is below 200 Bq/m³, it is within the Canadian guideline. Consider retesting within the next 5 years.

When your radon level is reported at 200 Bq/m³ or more, take action to REDUCE radon levels within one year.

The Canadian guideline for radon in indoor air is 200 Bq/m³

If you’ve tested your home, and the radon level is above the Canadian guideline of 200 Bq/m³, Health Canada recommends that you take action to lower the level.

The higher the radon level, the sooner action should be taken to reduce the level to as low as practically possible. While the health risk from radon exposure below the Canadian guideline is small, there is no level that is considered risk free. It is the choice of each homeowner to decide what level of radon exposure they are willing to accept.

RADON LEVEL LIFETIME RISK OF LUNG CANCER LIFETIME RISK OF LUNG CANCER IF YOU SMOKE
Under 100 Bq/m³ 1% 12%
100-199 Bq/m³ 1.5% 15%
200-599 Bq/m³ 2% 17%
600 Bq/m³ and over 4% 26%
