How can I tell if I have too much radon in my home?


Radon is tricky. You can’t see it, and you can’t smell it. So, the only way to know how much radon you have in your home is to get a test kit and do a test.

You can buy test kits at a lot of different stores — hardware, lawn and garden, outdoor supply, and department stores. They cost about $25 and take just a few days to do. Then you send your test kit in to a laboratory, and they tell you how much radon you have in your home.
