About Tobias Radon Testing, LLC

Tobias Radon Testing has been providing radon testing services to the home inspection industry, throughout New Jersey, since 2001. Established with the idea of assisting home inspectors with radon test collections, Tobias Radon Testing offers radon test placements as well.

Typically, the service begins when an inspector contacts Tobias Radon Testing, either by phone, fax or email, with basic information regarding the inspection. At this point, arrangements are made by Tobias Radon Testing to return to the house and retrieve the radon test. Once completed, a confirmation is sent to the inspector that the job is done.

Charcoal canister radon tests are the most common type used for inspections. Radiation Data is the busiest charcoal canister analysis lab in New Jersey. If you’re conducting charcoal canister tests from Radiation Data, Tobias Radon Testing will personally deliver the radon test back to their lab, within one day of the pick-up, at no extra charge.

Tobias Radon Testing is not limited solely to home inspectors. We also provide radon testing services to realtors and attorneys when additional radon testing is needed for real estate transactions, or to interested homeowners testing their houses for the first time.

Thank you for visiting the Tobias Radon Testing website. Please call for more information regarding our radon testing services and how they can save your company valuable time and expense of returning to homes previously inspected. New Jersey strictly regulates those who offer radon measurement, requiring state licensing as a Radon Measurement Technician. Mark Tobias holds NJ Radon Measurement Technician License MET10670.

What is Radon?

Radon is a natural radioactive gas that emanates from the ground into the air. It’s chemically inert, and has no odor, color or taste. It is produced from radium in the decay chain of uranium, an element found in varying amounts in all rocks and soil. When radon gas escapes from the ground into the air it emits heavily ionizing radiation called alpha particles. These particles are electrically charged and attach to aerosols, dust and other particles in the air we breathe. As a result, radon progeny may be deposited on the cells lining the airways where the alpha particles can damage the DNA and potentially cause lung cancer. Radon gas in the air is present worldwide, its concentration depending on the highly variable uranium content of the soil. It is the second most important risk factor for lung cancer, causing between 6 and 15% of all cases, yet, there is little public awareness of radon as a serious threat to human health.

What Effect does Radon have?

Although the average exposure to radon varies enormously, recent studies have shown that, when exposed to a radon concentration of 100 Bq (Becquerels)/m3, a non-smoker's risk of lung cancer by age 75 years increases by 1 in a 1000 compared to non-exposed people. Among those who smoke and are exposed to the same radon concentration, the risk of lung cancer is about 25 times greater. On a global level, tens of thousands of lung cancer deaths annually can be attributed to radon. Most of the radon-induced lung cancer cases occur among smokers.

Radon In Your Home

Due to dilution in the air, outdoor radon levels are usually very low. Radon levels indoors are higher and pose the greatest exposure risk for the average person. The concentration of radon in a home depends on the amount of uranium producing the radon in the underlying rocks and soils, as well as the routes available for its passage into the home and the rate of exchange between indoor and outdoor air. Radon gas enters houses through openings such as cracks at concrete floor-wall junctions, gaps in the floor, small pores in hollow-block walls, and also sumps and drains. Consequently, radon levels are usually higher in basements, cellars or other structural areas in contact with soil, and the radon concentrations in houses directly adjacent to each other can be very different. Radon exposure in homes can be easily mitigated during the construction of new homes, but existing buildings can also be protected from radon. Most measures such as increasing under-floor ventilation and sealing cracks and gaps in the floor require simple alterations to the building, but other approaches may have to be taken in areas with high radon concentrations. Overall, reducing radon exposure is an important contribution to the goal of good quality indoor air.
