Radon Credential Requirements by State
A state-by-state reference on radon credential requirements, recognized programs, and the governing authority for each state.
This reference is being prepared
The state-by-state credential dataset is in a verification pass and will be published on this page: which states require certification, licensing, credentialing, or registration for radon testing and mitigation, the recognized programs, and each state's governing authority.
For Iowa: radon measurement and mitigation performed for hire each require the applicable Iowa HHS credential, which can be verified with the state before hiring. More information is on the resources page.
