Radon Testing

Per the EPA’s Home Buyer’s and Seller’s Guide to Radon: ” Radon is a radioactive gas that has been found in homes all over the United States.  It comes from the natural breakdown of uranium in the soil, rock and water and gets into the air you breathe.  Radon typically moves up through the ground to the air above and into your home through cracks and holes in the foundation.  Radon can also enter your home through well water.”  Radon kills an estimated 15,000 people per year and according to the surgeon general is the second leading cause of lung cancer.   If you smoke and live in a house with high Radon levels, the risk of lung cancer is dramatically increased.  Refer to the EPA’s Home Buyer’s and Seller’s Guide to Radon for more information.


Radon is a colorless, odorless, tasteless, radioactive gas.

Inspection Technique 

White Blaze Home inspection employs the use of electret ion chamber detection technology (E-Perm®)for radon detection and measurement. It’s a passive device (requires no power source) that when exposed to radon gas and the results read by an analyzer, will provide a reliable and accurate report on the level of radon in the home.

Each short term home radon test consist of two test chambers positioned no more than 4 inches apart and left at the home for a period no less than 48 hours.  Prior to and during the testing, certain test conditions need to be adhered to.  These conditions will be explained and reviewed before the testing begins.  After the test period is completed, a computerized report will be available within one business day.  Being a certified Radon Measurement Specialist with the NRSB (National Radon Safety Board)  allows for same day results instead of sending the test units off to an outside laboratory and waiting for results to return.

Radon Measurement and Limits

Radon is measured in picocuries per liter (pCi/L) and congress has set a long term goal that indoor levels be no more than outdoor levels or about 0.4pCi/L.  EPA recommends fixing your home if the results of test show radon levels of 4pCi/L or greater.  With the present mitigation technology, most homes can be reduced to 2pCi/L or lower.   Refer to the EPA’s Consumer’s Guide to Radon Reduction for more information.
