Radon Test Kit

Works as advertised, basically you leave the sensor in a non-drafty lower level location for 48 hours and then mail it in. Results can optionally come back via email. My test results were a bit higher than expected but nothing to worry too much about. Had the results been worrisome then I would have contacted a state-licensed radon mitigation contractor to do a follow up test. Results arrived via email 3 days after mailing the kit.

Very simple instructions. The lab received my test kits on a Friday, and I had the results in my inbox on Monday. Very affordable (free test results).
