Radon Test Experts

Radon testing is an integral part of the radon mitigation process. Whether you’re a homeowner or live in a condo or apartment, we provide an effective solution for your radon gas testing needs.

What is Radon?

Radon is a colorless, odorless gas emitted from the ground and found in homes. It can enter your home through cracks in the foundation, openings around pipes and vents, or even from a basement. EPA estimates that every 1 in 15 homes have radon gas in the US. Your home could be one of them. They are tamed by having them tested for in Maryland.

Why is Radon Testing Important?

Radon gas testing is important because it detects the presence of radon gas and its entry passage into your home. Radon kills 21000 people every year by causing cancer, lung disease, and other respiratory ailments. EPA issued new guidelines for radon testing, and the importance of radon testing has been rising since then.

Acceptable Radon Levels?

The World Health Organization has set the action level for radon at 2.7 pCi/L, generally accepted as an acceptable level of radon exposure in homes for short-term exposure (less than 8 hours). If you are experiencing radon levels above 2.7 pCi/L, you should contact a professional to test your home. The EPA’s action level for radon in homes is four pCi/L, generally accepted as an acceptable level for short-term exposure (less than 8 hours). If you are experiencing radon levels above 4 Pc i/L, you should contact a professional to test your home.
