[Licence Number: RT820]

Why Get Tested

The U.S. Surgeon General has listed indoor radon as the second leading cause of cancer in the United States and the Environmental Protection Agency estimates that there are 21,000 radon related lung cancer deaths every year.

Radon is a naturally occuring radioactive gas and is produced when Uranium and Radium decay.  It occurs in many soils and rocks beneath any home and the gas can move easily through any porous material or in void spaces beneath any home.  It is a gas that is odorless, tasteless, and colorless.


Testing Guidelines

Homes should be in a closed house condition (all windows and doors are kept closed except for normal momentary entering and existing) for 12 hours before the start  of the test  and stays closed for a minimum  of 48 hours.  Heating or air conditioning can be operated during the test.


Every house that has been tested for radon that has resulted in a mitigation install should be retested every two years.

Any house with newly installed windows, roof, siding, and/or insulation should be retested for radon because the home is more airtight then it was before.
