  • One set of two monitors is required for each 2,000 sq. ft. in the lowest level that could be used regularly, whether it is finished or unfinished.

  • For large homes where the level of the home being tested is over 2,000 sq. ft., an additional set of two monitors is required for each 2,000 sq. ft. of the level of the home being tested.

  • If there is a crawl space under living spaces, another set of two monitors is required in the living space over the crawl space.

  • If there is a garage on slab with living spaces above the garage, another set of two monitors is required in the living space above the garage.

Do you know what you are breathing?

It is highly recommend to measure the indoor concentration level of radon in Montgomery, Howard, Frederick counties, in Northern Virginia and in the District of Columbia
.

We are using the Protocol for Conducting Radon and Radon Decay Product Measurements in Multifamily Buildings, developed by the AARST Consortium on National Radon Standards, an Approved American National Standard (ANSI).

Please contact us for detailed estimates 

 

The EPA recommends that you fix your home when the radon level is 4 pCi/L or more and we suggest that you contact a qualified radon reduction contractor about lowering the radon level if results of the above tests are over this threshold.

 

Another level set by the EPA is 2.0 pCi/L ("Consider Action Level"). At this level, the EPA recommends that you consider installing radon abatement systems in your home to reduce your indoor radon levels.
