Radon exposure, over time, is clearly associated with lung cancer. Reducing radon exposure is an important for cancer reduction, particularly if people are smokers or live with smokers in the home.
People should talk to their doctor about their radon levels if they are elevated (over the federal guideline of 200 Bq/m3).
Simple actions for Canadians to take include purchasing a radon test or hiring a professional to test their house for radon and then following up with their doctor about the results. Reducing smoking is, of course, important but so too is reducing radon levels if they are above the action level. There are clear steps on how to do this and there are certified professionals that can help.
