We finally got the radon results back from the test kit we left in the basement for months—4.0 pCi/L. That's right at the EPA action level, so we need to fix it. I've been reading up on mitigation systems, basically a fan and pipe setup that vents the gas out from under the slab. It's not a crazy expensive job, but it's one of those things you just can't ignore for your family's health.
