Buying a radon test kit usually runs between $10 and $30, but a professional measurement by a certified inspector can cost $150 to $800 or more depending on your location and home size. I went with a continuous monitor for around $300 because I wanted results over several days, and it gave me peace of mind knowing the levels were safe before finishing my basement.
