The Radon Problem in Indiana and Johnson County
Indiana is one of the highest radon risk states in the entire country. The United States Environmental Protection Agency has classified the majority of Indiana counties as Zone 1 radon risk areas — the highest possible risk designation. Johnson County where Johnson County is located falls within this high risk zone meaning Johnson County area homeowners face above average radon exposure risk compared to national averages.
Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It is colorless odorless and completely invisible making it impossible to detect without proper testing equipment. Radon enters homes through foundation cracks floor joints sump pits and other openings where the structure meets the soil. Because Johnson County Indiana sits on geological formations that are naturally high in uranium content the soil beneath Johnson County homes releases radon at higher than average rates.
The EPA recommends that every home in the United States be tested for radon regardless of age construction type or location. In high risk areas like Johnson County Indiana and Johnson County testing is especially critical. The only way to know if your home has a radon problem is to test.
What Is Radon and Why Is It Dangerous
Radon gas is produced when uranium naturally present in Indiana soil and bedrock breaks down. As radon decays it produces radioactive particles that when inhaled become trapped in the lungs where they release small bursts of energy that can damage lung tissue over time. This damage is what leads to lung cancer.
According to the EPA radon causes approximately 21,000 lung cancer deaths in the United States every year making it the second leading cause of lung cancer after cigarette smoking. Radon is responsible for more lung cancer deaths annually than drunk driving fires and drowning combined. Non-smokers who are exposed to high radon levels face a significant lung cancer risk and smokers exposed to radon face an even greater combined risk.
The EPA action level for radon is 4 picocuries per liter of air written as 4 pCi/L. Homes testing at or above this level should have a radon mitigation system installed. The average indoor radon level in the United States is 1.3 pCi/L. Indiana homes average significantly higher than the national average due to the state's geology. Many Johnson County Indiana homes test well above the 4 pCi/L action level especially in basements and crawl spaces.
Signs Your Johnson County Indiana Home May Have a Radon Problem
Your Home Has Never Been Tested
The most common sign of a radon problem is simply never having tested. Because radon is invisible and odorless the only way to know your exposure level is through testing. If your Johnson County home has never been tested for radon you should schedule a test immediately.
You Have a Basement or Crawl Space
Radon concentrations are highest in the lowest level of a home. Basements and crawl spaces are the primary entry points for radon gas. Johnson County Indiana homes with basements or crawl spaces face elevated radon risk compared to slab-on-grade construction.
Your Home Has Foundation Cracks
Cracks in foundation walls and floors create direct pathways for radon gas to enter your home from the soil below. Water damage that has caused foundation cracking can significantly increase radon entry points throughout your Johnson County home.
You Live Near River Corridors
The soil in low-lying areas near the East Fork White River and Driftwood River in Johnson County contains geological formations associated with higher radon production. Johnson County homes near these river corridors should prioritize radon testing.
Your Home Was Built Before 1990
Older Johnson County homes were built before radon awareness and EPA guidelines existed. These homes were not designed with radon resistant construction features and frequently test at higher radon levels than newer construction.
A Neighbor Has Had Radon Mitigation Done
Radon levels vary significantly from home to home even on the same street. If a neighbor has had radon mitigation installed it is a strong indicator that your neighborhood has elevated radon risk and your home should be tested immediately.
Our Radon Testing and Mitigation Process in Johnson County Indiana
Step 1: Radon Testing and Consultation

Step 2: Professional Radon Testing
We deploy professional radon testing equipment in the lowest livable area of your home in accordance with EPA and Indiana guidelines. Testing periods and methods are determined by your specific situation. We use certified testing equipment and follow all Indiana State Department of Health radon testing protocols to ensure accurate reliable results.
Step 3: Results Review and System Design
When testing is complete we review your results with you and explain exactly what the numbers mean for your family's health. If your home tests at or above the EPA action level of 4 pCi/L we design a custom radon mitigation system specifically for your Johnson County home's construction type foundation and radon entry points.
Step 4: Radon Mitigation System Installation

Step 5: Post-Mitigation Testing and Verification
After installation we conduct post-mitigation testing to verify that the system has successfully reduced radon levels in your Johnson County home below the EPA action level. We provide you with documentation of both pre and post-mitigation radon levels for your records insurance purposes and future real estate transactions.
