Reduce Your Risk

The lower the radon concentration in a home, the lower the risk of it causing lung cancer.


Here is how to check your home for dangerous levels of radon and where to go for help.

The Government of Canada recommends that the radon levels in a building should not be higher than 200 Becquerels per metre cubed (Bq/m3).


Test your home!

Radon has no colour, smell or taste. The only way to know if there are high levels of radon in your home is to test.Testing is best done in colder months, when your home is sealed, rather than in the summer when windows and doors are open.

  • 96% of Canadians have not tested their homes for cancer-causing radon gas.
  • Please visit our Radon Resources page for information on ordering a testing kit.

Take action

If your test results show high levels of radon, you should take action to lower the level as soon as possible.

Techniques to lower radon levels are effective and can save lives. A radon mitigation system can be installed quickly and in most homes will reduce the radon level by more than 80%.

A "C-NRPP" certified professional can help you work out the best way to take care of the radon problem in your home. You can visit the following websites to find info on certified professionals and testing devices:

Canada’s 2010 National Building Codes include requirements that address the reduction of radon entry into homes. These codes require a "rough-in" for a radon reduction system. This lowers remediation costs if action has to be taken at a later date to reduce radon levels in the home. **Please note that if you have a "rough-in" in your home, you still need to test your home and have the reduction system activated if your radon level tests high.

Higher levels of radon are mostly found in the Interior and Northern parts of the province, but everyone is encouraged to get their home tested.

In October 2020, Take Action on Radon held a webinar for a group of people about to test their homes. There is excellent information in this webinar from minutes 3 to 20, however you may wish to watch the whole webinar to hear the Q&A as well.
