Iowa Radon Levels
EPA Radon Levels
Iowa has 98 counties and 98 (100%) 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. Iowa's state radon zone average is 1, which is the average of all county zone ratings the EPA has assigned the state, ranking it 1 among all states.
The radon levels in the entire state of Iowa are above average. It has been identified by the US EPA as a zone 1 state, which means that at least 50% of the homes have tested above the recommended action level. Long story short, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Iowa Radon Contractor License Information
Does Iowa require contractors to be licensed? Yes.

- Attend and complete an approved qualification course.
- Obtain proof of certification and NRPP listing, and include it with application from the next step.

Iowa Radon Real Estate Requirements
Does the state of Iowa require radon testing for all real estate transactions? No
However both the state of Iowa and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Iowa 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. Iowa radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
Iowa Radon Map
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.
Iowa is the 26th most expansive state in terms of area, and is also the 30th most populous.
