Radon Testing

Radon is a radioactive gas that occurs from the natural breakdown of uranuim in soil and rock.  Most homes have some amount of radon present, though it is odorless, colorless, and tasteless.

Health Risk Information

Radon is the second leading cause of lung cancer, after smoking. According to the United States EPA, an estimated 20,000 lung cancer deaths are caused by radon every year.

There are several ways that radon enters the home:

  • Cracks in floors
  • Construction joints
  • Cracks in walls
  • Gaps in suspended floors
  • Openings in service pipes
  • Cavities inside walls
  • Water supply

Acceptable Level

The acceptable level of Radon in your home, or school, or workplace is 4 pCi/1 and below.  The unit pCi/1 refers to picocuries per liter, the standard method of reporting radon levels in the United States.


The EPA recommends that your radon level be tested every couple of years.  Generally, short-term tests are performed over a two to four day period.  The two methods we use for short-term testing are E-Perm radon electret kits and charcoal canisters.  For long term testing (over 90 days) we use Alfa Tract Detectors.

The E.P.A. recommends that your radon level be tested every couple of years.
