Home Radon Testing for Arlington, VA

The EPA recommends that all homes be tested for radon. The D.C., Maryland, and Virginia area have been identified by the EPA as an area with a higher potential for elevated radon levels. See map for radon zones per the EPA.

Radon is a naturally occurring radioactive gas that is odorless, tasteless, and invisible. It typically moves 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 and your home can trap radon inside. Any home can have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes without basements can have radon. 90% of the land in the Northeast and a majority of the Mid-Atlantic is likely to have elevated radon levels. If not tested, radon can pose a serious danger to your family’s health being the leading cause of lung cancer among non-smokers.

By having Donofrio & Associates, LLC. test your home for radon, you will have peace of mind knowing the levels of radon.

Our Radon Detection Process

We use a 48-hour Active Continuous Radon Monitor that takes hour by hour measurements. This is placed in the lowest habitable area of the home, typically a basement. The monitor has built-in anti-tampering devices and should not be touched. Normal living conditions can resume during the test, however and it is recommended that all doors and windows be closed 12 hours prior and while the radon machine is running. A report will be provided after the testing period. Click here for a sample report.
