radon testing 2

You won't know you have a radon problem in your home unless you test for it. The test is easy to do and inexpensive.

Two radon tests recently done in my basement came back well within the allowable limit. The Canadian guideline for radon is 200 becquerels per cubic metre.

About 10% of Canadian homes are above this limit.

My results are 111 and 137 Bq/m³.


The reports (both from AccuStar) state that this test has an uncertainty of plus or minus 15%. I plan to repeat the test at some point.

I read somewhere that radon tests are required for real estate transactions in some US jurisdictions, but not yet in Canada.
