You can either test your home yourself or hire a certified Radon testing professional.
If you choose a do-it-yourself home Radon test, you have a couple of choices. These choices are between a short-term or long-term test device. In either case, the best time of year to test is during the heating season (October – April). This is generally the period where our homes and buildings are more tightly sealed up and the radon levels would likely be at their highest.
Both are easy to use and come with step-by-step instructions. Keep in mind, however, that Radon levels are not consistent and therefore a short-term test may not necessarily represent your “annual average exposure levels” which is why Health Canada recommends “long-term test devices” to test your annual average Radon exposure levels.
