My Long Relationship with One Serious Health Risk – Radon

By Lou Witt

January is National Radon Action Month — a key time to focus on a year-round effort — and I’ve seen a lot of them. For more than 18 years, I have worked to improve indoor air quality; much of that time focused on radon risk reduction. Unfortunately, for more years than I’d like to mention, I’ve probably been exposed to elevated levels of radon and didn’t even know it.

Growing up, I spent innumerable hours in our basement play/party room — often with family and friends — ignorant, but blissful. How much radon was I exposed to? I don’t know; No one knew to test. It was probably higher than I’d like to think about as our home was in an area with high radon potential.

Fortunately, when I bought my own home, I knew to test regardless of location. I may even vaguely remember that it was quickly mentioned during the sale. When I tested the lowest floor of my home, my result was 18 picocuries per liter of air of radon –—pretty far above EPA’s action level of 4 pCi/l. Since I spent very little time in the cellar — it’s really not a livable space — I measured on the first floor. It was right below 4 pCi/l. A lower number would have been better, but at least I’m under EPA’s action level.

Radon is one health risk we can all avoid and it’s simple. Test your home and fix the problem. Mitigating a radon problem costs about the same as other household repairs and this change can save your life.
