Have you received your radon test results? Use this letter template to inform client families about the results of your centre’s radon testing. This “below guideline” letter is for use by centres that have tested below the Health Canada guideline for acceptable radon levels.


Dear Parents and Guardians,

As you know, our centre recently conducted a test to determine the level of radon in the indoor air. We decided to take this voluntary measure because of our commitment to providing the safest possible environment for the children in our care.

We are pleased to inform you that the level of radon in our centre is below the Health Canada guideline. The level reported to us by the laboratory is [insert number] bequerels per cubic metre of air (Bq/m3). A bequerel is a meaure of radioactive decay. Health Canada recommends that action be taken to reduce radon in indoor air if levels are above 200 Bq/m3.

Radon is an odourless gas that comes from uranium in the ground. Radon can move into buildings through cracks and gaps in the foundation where it can build up to harmful levels. Long-term exposure to radon increases the risk of developing lung cancer.

We’d also like to take this opportunity to remind you that elevated radon levels can also be present in homes. So if you have not already tested your home for radon, we encourage you to do so. We’d be happy to share information on how to test for radon – it is a very simple process. Ensuring acceptable radon levels in homes and learning environments is the best way to protect children from the long-term lung cancer risk associated with elevated radon exposure.

If you are interested in learning more about radon, including how to test your home, please contact [name] at [insert contact info]. Information on radon can be found on the Health Canada website at healthcanada.gc.ca/radon and at www.reduceradon.ca.

Yours sincerely,
