    Radon is a naturally occurring gas that emanates from the soil and groundwater. It is invisible, odorless, and tasteless, but presents a serious health risk to homeowners and their families. According to the EPA, one in fifteen buildings nationwide has elevated levels of radon gas. Every year, over 20,000 Americans die from radon-related lung cancer.

    Fortunately, the threat posed by indoor radon is fully preventable! Regularly testing for radon exposure and applying well-established venting techniques nullifies this health hazard. At GeoServices Inc, we utilize various testing methods to measure the level of radon in your home or business, and offer proven strategies for restoring your private or professional environment.

    Radon Testing Residential & Commercial

    GeoServices Inc provides an array of radon testing services. For multifamily residential and larger commercial and institutional buildings, we utilize charcoal canister testing or Alpha track long-term testing canisters. For real estate transactions and mitigation retesting, we utilize Sun Nuclear continuous radon monitoring equipment. In addition to testing for the presence of radon in breathable air, we also test for radon in water.

    Depending on the type of testing used, it may take between 48 hours and several weeks for the results to come in. Consult our expert technicians to better understand the difference between the available methods, and choose the one suitable for your environment.

    Radon Mitigation Residential & Commercial

    If testing shows an elevated presence of radon in your environment, there are ways of bringing it back down to an acceptable level. At GeoServices Inc, we offer a number of mitigation techniques, all highly effective and relatively inexpensive. Give us a call, and we'll help you decide which one works best for your home and your budget.

    The most popular methods involve active soil depressurization (ASD). A ventilation system draws soil gas out of the foundations, expelling it safely outside so it cannot accumulate inside the building.

    Other approaches include mechanical ventilation heat recovery (MVHR). A continual airflow vents the gas outside, using the exhaust for heating purposes (particularly cost-efficient in cold climates).

    Finally, radon accumulated in water dissipates gradually over time, but very slowly. To make this process more efficient, activated charcoal systems (ACS) are available.
