Radon Testing and Mitigation

Radon Testing

The amount of radon in the air is measured in “picocuries per liter of air” or pCi/L.  There are many kinds of low-cost “do it yourself” radon test kits you can get through the mail and in hardware stores and other retail outlets. Here is a coupon that can be used to purchase in home test kits: VDH Radon test kit coupon or you may purchase a test kit online with a credit card at: Virginia Radon Test Kit

Make sure you buy a test kit that will be analyzed by a laboratory listed by either of the two proficiency programs listed below:

The National Radon Proficiency Program (NRPP)

If you prefer, or if you are buying or selling a home, you may hire a trained professional to perform testing for you.  Make sure you hire a qualified radon tester listed with either NRPP or NRSB.

Radon Mitigation

A variety of methods are used to reduce radon in your home.  In some cases, sealing cracks in floors and walls may help to reduce radon.  In other cases, simple systems using pipes and fans may be used to reduce radon.  Such systems are called “sub-slab depressurization” and do not require major changes to your home.  These systems remove radon gas from below the concrete floor and the foundation before it can enter the home.  The right system depends on the design of your home and on other factors.

Ways to reduce radon in your home are discussed in EPA’s “Consumer’s Guide to Radon Reduction” at EPA’s Guide on Radon Reduction Techniques for your Home

The cost of making repairs to reduce radon depends on how your home was built and the extent of the radon problem.  Most homes ca be fixed for about the same cost as other common home repairs like painting or having a new hot water heater installed.  The average house costs about $1,200 for a contractor to fix, although this can range from about $500 to about $2,500.

Lowering high radon levels requires technical knowledge and special skills.  You should use a contractor who is trained to fix radon problems.  Virginia State Law requires radon contractors who install radon reduction systems to be listed with either the National Radon Proficiency Program (NRPP): www.nrpp.info , or the National Radon Safety Board (NRSB): www.nrsb.org.
