What is Radon Testing Labs Inc?

Since 1988 Radon Testing Labs, Inc. (RTL) has been synonymous with quality and service.  We are the largest full-service radon company in North Carolina, offering do-it-yourself test kits, continuous radon monitoring, and radon remediation.   RTL is owned and operated by Dr. Zygmunt C. Gromadzki, who received his Ph.D. in Nuclear Physics from the University of Virginia.  He is also certified by the American Board of Radiology, and has spent over 20 years in the treatment of cancer patients using radiation therapy.  Dr. Gromadzki is a recognized expert in radiation and radiation safety, radioactive materials, and radon, and is the author of numerous publications and articles on these subjects.

Who uses our services?

Homeowners, Realtors, and home inspectors purchase our short-term exposure charcoal canister test kits to test homes for the presence of radon.  Or they have us test the home using a continuous monitor, a device that measures the radon level on an hourly basis and prints out the results at the end of the test.  When elevated levels of radon are found, we mitigate the home to bring the level below the EPA’s Action Level of 4.0 picoCuries of radon per Liter of air (4.0 pCi/L).

Is there a certification agency for radon-related companies?

There are two: NEHA-NRPP (National Environmental Health Association-National Radon Proficiency Program), which took over the former EPA Radon Proficiency Program in 1996, is the larger of the two; the other is NRSB (National Radon Safety Board).  RTL is the ONLY Raleigh-area company that is certified in all three NEHA-NRPP categories: as an analysis laboratory for short-term charcoal canister test kits (# 101091 AL), as a radon testing company using charcoal test kits and continuous monitors (# 100780 RT), and as a radon mitigation company (#100778 RMT).   We have also been a member of AARST (The American Association of Radon Scientists and Technologists) since its inception.
