Rn Questions Answered
What is radon?
Radon is a gaseous radioactive element produced by the decay of naturally occurring uranium found in soils throughout the world. It is extremely toxic, colorless, and is only detectable by specialized equipment. Every homeowner should test for radon.
How high is too high?
The outside air averages 0.4 pCi/L while most structures contain higher levels. Levels in homes often range from a few pCi/L to well over a hundred in some cases. At 4.0 pCi/L the EPA recommends mitigation. At 20 pCi/L the risk of lung cancer becomes 35 times the risk of drowning. One of the highest recorded cases in Amercia measured 3700pCi/L in Pennsylvania. Radon is the leading cause of lung cancer in non-smokers.
Why does my home have high radon?
The amount of radon in the soil depends on soil chemistry which varies from one house to the next. Radon propagates up through the ground and into your home through even the finest cracks and holes. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.
Each home must be tested individually to determine radon levels.
How is radon measured?
The amount of radon in a home is measured in units of pCi/L (picocuries per liter). Testing is available from a variety by professionals including home inspectors and radon testing companies. Consumers may also purchase accurate and simple test kits from many hardware stores and other retailers. In each case testing is easy and inexpensive.
How can radon levels be reduced?
Regardless of the size or type of home, radon levels can be reduced effectively and affordably by installing a well-designed radon mitigation system. We always recommend dealing with a NEHA/NRPP certified radon mitigation company. Refer to for more information. Stanton Engineering Solutions, Inc. is fully certified.

How often should I test/retest?
The EPA recommends testing your home when first acquired and every 2 years thereafter. You should also retest after additions to your home or changes to the HVAC system. Radon levels will often become higher during the winter months.
