You buy a home radon test at a hardware store or online, usually a small charcoal or alpha-track device that sits in your basement for a few days to a few months. After you mail it to a lab, they measure the radioactive gas that seeps from soil into your house. It’s a straightforward way to check a hidden health risk, since radon is the second leading cause of lung cancer, and you cannot smell or see it.
