Indiana Specific Radon Information: Radon in Indiana
What is Radon?
Radon is a colorless, odorless, tasteless, radioactive gas produced by the natural decay of uranium and radium in the soil. Exposure to elevated radon levels increases the risk of developing lung cancer. The EPA estimates that 21,000 lung cancer deaths each year in the United States are due to radon, making it the leading cause of lung cancer among non-smokers.
The United States Environmental Protection Agency (USEPA) recommends that indoor levels of radon remain below 4.0 picocuries per liter of air (pCi/L) to decrease the risk of developing radon-induced lung cancer.
What is the risk in Indiana?
All counties in Indiana are located in Zone 1 or Zone 2, indicating Indianans have a medium to high potential for elevated levels of radon gas.
Some homes in Indiana have been found to have radon levels over 80 pCi/L, posing an extremely high risk for occupants.
Nationally, more deaths are caused by radon induced lung cancer than the top five causes of accidental home injury deaths combined (falls, poisoning, fires, choking, drowning).
The USEPA estimates that 1 in 15 houses in the USA contain elevated levels of radon.
How can you test your home for radon? Do-It-Yourself radon test kits are low cost and easy to perform. Short-term test kits lasting 3-7 days or long term test kits lasting 1-12 months can be obtained from the American Lung Association of the Upper Midwest by clicking on this link or by calling 1-800-788-5864. When testing, be sure to follow directions on placement and time period closely and contact the Illinois Radon Program or company that produced the kit with any questions regarding the testing procedure or interpreting the results.
If you do not want to perform the testing yourself, a list of Indiana licensed radon testing professionals that service your county can be found on the Indiana State Department of Health by clicking here.
How do you fix a radon problem? If tests show that your homes radon levels are above 4.0pCi/L it is suggested that you get a radon mitigation system installed. The most common and effective type of mitigation system is a vent pipe and fan system that draws air from underneath the foundation of the house and disposes of it outside. This radon mitigation system removes radon from under the foundation and vents it above the roof line of the house so that it does not enter the home.

The cost of a radon mitigation system can range between $800 and $2,500 (average $1,200) dependent upon characteristics of the building and the choice of radon reduction method.
How do you become licensed for radon services in Indiana?
To perform radon related services (measurement or mitigation) in the state of Indiana, you MUST be licensed by the Indiana State Department of Health (ISDH). Becoming licensed by ISDH is a 3 step process:
Take and pass a nationally certified radon measurement or mitigation course. You can check the USEPA website for Regional Radon Training Centers by clicking here or take an online course.
Once you obtain your NRPP certification for measurement and/or mitigation, you are then eligible to apply for your Indiana Radon License. License application is available through the ISDH website or by clicking here.
