Radon is a colorless, odorless radioactive gas that rises from the soil and enters homes through foundation cracks, sump pits, and floor-wall joints. We measure it with a continuous radon monitor placed on the lowest livable level under closed-house conditions, recording hourly readings over at least 48 hours.
Results are reported in picocuries per liter (pCi/L) and compared against the EPA action level of 4.0 pCi/L. It's a quick, valuable add-on to a full home inspection. Learn more about radon testing or about home inspection in Hector, MN.
