We had a contractor install a radon reduction system in our basement last year. It's basically a fan and pipe setup that pulls soil gas from under the slab and vents it above the roofline, keeping the radioactive gas from entering our living space. The difference in our air quality readings before and after is night and day—our test went from 8 pCi/L down to 0.5. It runs quietly and costs just a few dollars a month in electricity.
