Clarksville, Tennessee, sits atop the Highland Rim geological region, where high levels of radon gas are a documented concern. Radon is a naturally occurring radioactive gas that seeps up from uranium-bearing granite and shale deposits in the soil. The U.S. Environmental Protection Agency (EPA) has designated Montgomery County (where Clarksville is located) as a Zone 2 area, meaning predicted average indoor radon levels may be moderate but can still exceed the action level of 4.0 pCi/L. Many homes in Clarksville’s older neighborhoods, as well as newer subdivisions built on fractured limestone, have tested at elevated levels. With a growing population (over 170,000 residents), an active real estate market driven by Fort Campbell military families, and increasing awareness of radon health risks, there is a steady demand for professional radon testing. Homebuyers frequently require radon tests as part of their home inspection contingency, and existing homeowners are increasingly proactive about testing. Starting a radon testing business here offers a solid local niche with low overhead and recurring opportunities from real estate transactions.
Tennessee does not require a state-level radon testing license at this time. However, to build credibility and meet industry standards, you should obtain certification from the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). These certifications involve passing an exam and completing continuing education. Many real estate agents and home inspection companies in Clarksville will only work with certified professionals.
You must register your business with the Tennessee Secretary of State and file for a business license with Montgomery County or the City of Clarksville. Check with the Clarksville-Montgomery County Regional Planning Commission for local business tax requirements. You may operate as a sole proprietorship, LLC, or corporation. An LLC is recommended for liability protection.
Obtain general liability insurance (minimum $1 million) and professional liability (errors & omissions) insurance specific to radon measurement. Many Clarksville real estate offices require proof of insurance before they will refer clients.
Although the EPA does not license testers, you must follow the EPA’s Protocols for Radon and Radon Decay Product Measurements in Homes when conducting tests. Provide clients with the EPA’s “Home Buyer’s and Seller’s Guide to Radon” as part of your report.

In the Clarksville market, radon testing prices typically range from $150 to $250 for a standard short-term test (2–7 days) using a charcoal canister or continuous radon monitor. Long-term tests (90+ days) are priced $100–$150. Real estate transactions often demand quick turnaround, so you can charge a premium for same-day or next-day deployment (e.g., $200–$300). For multiple tests in one house (basement and first floor), offer a second test at half price. Keep an eye on competitor pricing by searching “radon testing Clarksville TN cost” and adjusting slightly lower initially.
