Cracked open the envelope from the lab this morning and my radon test results came back at 2.7 pCi/L, which is below the EPA action level but still got me thinking about that musty smell in the basement. The short-term test we did over the winter gave a different reading than the long-term one from summer, so I'm planning to run another test after sealing some foundation cracks.
