What Is Radon and Why Does It Matter?

Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It seeps into homes through cracks in the foundation, gaps around pipes, sump pits, and other openings in the building envelope. Because radon has no color, smell, or taste, the only way to know your radon level is to test.

The EPA recommends taking action when indoor radon levels exceed 4 picoCuries per liter (pCi/L). Indiana is a high-radon-potential state — many counties in Northwest Indiana fall in EPA Zone 1 and Zone 2, meaning elevated radon concentrations are common. Long-term radon exposure is responsible for approximately 21,000 lung cancer deaths in the United States each year.

Hawk Home Inspection provides certified radon testing using calibrated, professional-grade equipment. Following the test, you receive a clear report of your radon levels and, if necessary, guidance on appropriate mitigation steps. All testing protocols follow EPA and Indiana Department of Health standards.

Common Questions

Radon Testing FAQ

What radon level is considered safe in a home?

The EPA action level is 4 picoCuries per liter (pCi/L). Levels between 2–4 pCi/L are worth considering for mitigation. No level of radon is completely risk-free, but levels below 2 pCi/L are considered low risk. The average indoor radon level in the U.S. is about 1.3 pCi/L.

How long does a radon test take?

Short-term tests take 48–96 hours with results typically available within 24 hours of lab receipt. Long-term tests run 90+ days for a more accurate annual average. For real estate transactions, the 48-hour closed-house short-term test is the standard approach.

Is Northwest Indiana at elevated risk for radon?

Yes. Indiana is classified as a high-radon-potential state, with many counties in the Northwest Indiana region falling in EPA Zone 1 and Zone 2. The geology of the region — glacial soils with uranium-bearing deposits — contributes to elevated radon potential. Professional testing is strongly recommended for all homes.

What happens if my radon level is above 4 pCi/L?

Levels at or above 4 pCi/L require mitigation. A licensed radon mitigation contractor installs a sub-slab depressurization (SSD) system that vents radon from beneath the foundation to the outside. Mitigation typically costs $800–$2,500 and reduces levels by 50–99%. Post-mitigation testing confirms the system is working.
