New Jersey Professional Radon Inspection

Radon, a decay product of Uranium, is a naturally occurring radioactive gas found in the soil. Within the ground, Radon gas rises to the surface and is able to penetrate the concrete slab and foundation walls of a home. Although radon gas itself is not harmful, it’s radioactive decay products (polonium being the most harmful) plate out onto dust particles in the air and are breathed in. Studies have shown that high concentrations of radon gas can lead an increased risk for lung cancer.

One way for testing for this harmful radioactive decay product is using an activated charcoal canister. The canister is placed in the lowest occupied level of the home for a duration of 2 to 7 days. Then, the activated charcoal canister is sent into the lab for testing. From the start of testing, results are typically received within 1 week (Monday through Friday). Inspector Seltzer is affiliated with RA DATA, a local Radon and water testing treatment company located in Flanders, NJ.

Ideal results are concentration levels under 4.0 pCi/L(picocuries per liter). 4.0 pCi/L or higher is the EPA’s(Environmental Protection Agency) recommended action level. If results are above 4.0 pCi/L, the recommended action is to install a radon mitigation system. A radon mitigation system consists of PVC pipe(s) that penetrate the foundations concrete slab. A fan is attached to the pipe creating a vacuum under the slab. Radon gas coming up from the ground is diverted into the PVC pipe and exhausted to the exterior of the house . Basic mitigation systems run about 1800 dollars which create a significant drop in radon concentration levels within the home.

Mike has been testing for Radon gas in New Jersey the past 4 years. All of New Jersey’s Municipalities have seen high concentrations of Radon gas. The map given by New Jersey’s DEP (Department of Environmental Protection) indicates the highest concentration levels in the North West region of the state dissipating to the South East. Inspector Seltzer has seen ranges from < 0.2 pCi/L to 70.2 pCi/L. No matter the Radon level within your home, solutions are always available to bring concentration levels down to a permissible level.
