Odd, but true. Right now it is a state level issue.
The feds have not jumped on board yet.
Apparently high concentrations of radioactive radon gas have been linked to increases of lung cancer in non-smokers. In most cases it only reaches hazardous levels in the winter months when the house is buttoned up.
Opening a window for an hour once a month is sufficient to keep levels safe, but typical of government regulations you must install a permanent venting solution. A radon test is required when a house is sold. If the levels are above X a vent must be installed.
Our real estate agent told us to open a basement window for 2 days prior to the test and we would not have to deal with it.
My ex-wife closed the windows on me, it was a cool September, and we failed by the thinnest of margins.
