Testing for radon is easy and inexpensive. There are two ways to test a home for radon: 

1. Purchase a do-it-yourself radon test kit (available at most hardware stores). Be sure to follow instructions for setting up the test. 
2. Hire a certified, radon-measurement professional. 

Radon levels vary by day and week, so it’s important to measure radon frequently. Health Canada recommends testing for at least three months, between October to April.  

Some public libraries lend radon monitors. These are different from radon test kits, and should be used a as first step to determine if you should compete a full radon test. The Haliburton County Public Library and the Trent Hills Public Library (Campbellford) will have radon monitors available for residents to borrow starting in October 2023.  

What you do depends what the test tells you about how much radon there is. Radon is measured in becquerels per cubic metre (Bg/m 3). The Canadian guideline is that anything over 200 Bg/m3 requires action. The higher the level of radon, the sooner it needs to be addressed. You can contact a certified radon professional to figure out the best and most cost-effective way to reduce in your home.
