Reliable Radon Testing in Ashwaubenon

If your test results show levels below 2 pCi/L, no immediate action is needed, though periodic retesting is still recommended. Levels between 2 and 4 pCi/L fall in a gray zone where the EPA suggests considering mitigation, especially for long-term occupants. Results at or above 4 pCi/L call for prompt action, including a follow-up test to confirm and then installation of a radon mitigation system.

Before testing, you should maintain "closed-house conditions" for at least 12 hours prior to and during the test. This means keeping windows and doors closed except for normal entry and exit, and not operating fans or ventilation systems that draw outside air into the home. Avoid placing the test device near drafts, exterior walls, or high-humidity areas like bathrooms, as these conditions can affect accuracy.

A sub-slab depressurization system works by inserting a pipe through the concrete slab of a home's foundation and connecting it to an electric fan. The fan creates negative pressure beneath the slab, drawing radon gas out from the soil before it can enter the living space, and venting it harmlessly above the roofline. This is the most widely used and effective radon mitigation technique for homes built on slabs or with basements.

There is technically no "safe" level of radon, but the EPA recommends taking action to reduce radon in your home if levels reach 4 pCi/L or higher. The average indoor radon level in the United States is approximately 1.3 pCi/L, while outdoor air typically measures around 0.4 pCi/L.

Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year according to the EPA. When radon gas is inhaled, it decays into radioactive particles that can become trapped in the lungs, where they emit radiation that damages lung tissue over time. The risk increases significantly with long-term exposure to elevated radon levels, particularly in enclosed, poorly ventilated spaces.
