radon test st louis 3

My wife and I bought an old brick house in St. Louis, and our realtor insisted on a radon test before closing. It's common around here because of the limestone bedrock. We got a simple charcoal canister, left it in the basement for a few days, then mailed it to a lab. The results came back under the EPA action level, thank goodness, but I still bought a digital monitor to keep an eye on things year-round.
