HOW DO I TEST FOR RADON? (SOME INS AND OUTS ON DEVICE PLACEMENT)
Having a reliable, approved radon test device is important, but won’t mean much if it’s not correctly deployed. The idea behind deployment of the radon testing device is to try to obtain a representative measure of the radon levels occupants are exposed to. Health Canada recommends testing in the lowest lived-in level of the home (i.e., the lowest level that is used or occupied for more than four hours per day). In some homes this will be the basement, in others it might be the main floor.
There is nothing to say that more than one level of a home can’t be tested. The lowest lived-in level is considered a minimum.
This then leads to the question of where on a level is it appropriate to test. There are many considerations. Proximity to walls, ceiling, floors, windows, vents, the type of room, to name a few. Ideally, we want to test in the breathing space of room, but this is not always practical. A home test kit will generally provide comprehensive written guidance on where to place the detector.
But, there are some considerations you won’t find in the documentation. We have had instances where an alpha track detector doubled as an air hockey puck, a cat toy, or a target for karate kick practice.
If you’ve bought a radon home test kit and have questions, let me know. I love talking about this stuff and am happy to help.
