Radon sampling is done with a continuous radon monitoring machine or with a radon test kit. The radon machine is more expensive, but provides an hourly reading, is more accurate, and can be set up in advance so that results are available the day of the home inspection.

Is it important to test for radon?

Statement by the American Cancer Society:

Long term exposure to radon can lead to lung cancer. Radon in the air breaks down quickly, giving off tiny radioactive particles (radon progeny). When inhaled, these particles can lodge in the lining of the lungs, where they can damaged the cells there. This may eventually lead to lung cancer.

Statement by the Environmental Protection Agency:

EPA estimates that about 20,000 lung cancer deaths each year in the U.S. are radon related. Exposure to radon is the second leading cause of lung cancer after smoking. Radon is an odorless, tasteless and invisible gas produced by the decay of naturally occurring uranium in soil and water.
