Indiana Radon Information

Indiana Radon Program:

Radon Website: Website
Radon Contact: Jeff Turner
Active Radon Program: Yes
Require License for Radon Professionals: Yes

Indiana is the 38th largest in terms of area, and is also the 16th most populous. The state maintains a commendable radon program, and they have plenty of information listed on the official site.

The radon levels in Indiana are above average in certain areas of the state. That means there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Indiana Radon Levels

Map of Indiana Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

Indiana Radon Statistics

Indiana has 90 counties and 56 (62%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Indiana's state radon zone average is 1.38, which is the average of all county zone ratings the EPA has assigned the state, ranking it 13 among all states.

Indiana Radon Contractor License Information

Does Indiana require contractors to be licensed? Yes.

What are the licensing requirements? The requirements are as follows:

  1. Attend and complete an approved qualification course.
  2. Obtain proof of certification and NRPP listing, and include it with application from the next step.
  3. Submit certification application, along with the non-refundable fee to the Indiana Department of Health, attention to the cashier’s office.

Indiana Radon Real Estate Requirements

Does the state of Indiana require radon testing for all real estate transactions? No

However both the state of Indiana and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Indiana does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Indiana radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
