How to Use a Home Radon Detector
Radon is a naturally occurring radioactive gas emitted into the environment when the uranium in rocks, soil and water breaks down. Radon is a known carcinogen. The U.S. Environmental Protection Agency estimates that thousands of lung cancer deaths each year are attributable to high levels of the invisible, odorless gas in homes. A radon test kit is an easy and inexpensive way to determine if the level is safe in your home. Does this Spark an idea?

Tips & Warnings
Testing should be done during cooler months but never during stormy, windy weather. Ideally, two short-term home radon tests should be conducted simultaneously to determine the average home radon level.
Radon readings at or above the EPA action level of 4 pCi/L are considered unsafe. Corrective measures should be taken to reduce levels in the home. Radon test kits should be purchased from a qualified lab and must be used according to directions to achieve a reliable result. State radon offices and qualified radon professionals should be consulted for more information.
