Before we knew of radon and had radon testing equipment, we had nothing.
And people have lived a very long time in homes that had never been
tested.

They lived with asbestos, lead and radon. Chances are, if your ancestors
had longevity you will too. Unless of course you're the exception
because you spent half your nights worrying about something your
ancestors never had to..

Open a window, breathe in the air and enjoy life....
