Radon Testing


NOTE: Free radon test kits are no longer available. The limited supply has been distributed.


Radon causes lung cancer. It is the #1 cause of lung-cancer in non-smokers.

If you smoke and your home has high levels of radon the risk of developing lung cancer is 1 in 3.


The only way to know the radon level in YOUR HOME is to test for it!


Radon Kit

The Grey Bruce Health Unit is participating in a Radon Awareness Campaign with Health Canada. The objective of the project is to raise awareness about Radon and to get a better understanding of Radon levels throughout the Grey Bruce Health region. It is not known if there is a Radon concern in any particular community or home. However, as a precaution and to raise awareness as many homes as possible are being encouraged to test.


Kits are available at local home building stores and online through the Take Action on Radon and Lung Association websites.


Call the Health Unit 519-376-9420 or check out our website for more information.

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

If you’ve tested your home, and the Radon concentration is above the Canadian guideline of 200 Bq/m3, Health Canada recommends that you take action to lower the concentrations. The higher the Radon concentrations, the sooner action should be taken to reduce levels to as low as practically possible.

Radon Level Graphic

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.
