Health Canada is recalling two brands of radon detectors over inaccuracies in their readings, the agency said in a notice.
Two models of the Life Basis brand radon detectors and one model of InkBird Wifi Radon Detector were recalled on Friday over inaccurate radon detection, which Health Canada said could be a chemical hazard.
Radon is a colourless, odourless and tasteless gas that comes from the breakdown of uranium in soil and rock. In enclosed spaces, like homes, it can accumulate to high levels and become a risk to your health.
