Updated October 2, 2026
Short answer
Radon professionals in Arizona, in brief
No business that Arizona itself licenses or certifies is listed on Radon411 yet. Ask Arizona Department of Health Services what it requires before you hire.
The rule
Does Arizona license radon professionals?
Arizona's radon program page, checked on September 25, 2026, does not say whether the state licenses or certifies radon professionals. Ask the program before you hire.
Arizona is not on the list of states with radon credentialing programs that EPA's state contacts page publishes. Licensing is done by the state, not by the national programs, and EPA requires states that receive radon grants to give the public a list of only those providers credentialed by the state or by NRPP or NRSB.
Radon411 reads no licensing list for Arizona; Arizona's radon program is the place to ask who works there.

How to check a credential in Arizona
Arizona's own list
Start with Arizona's radon program. Licensing is done by the state, and most states can give you a list of radon service providers working there.NRPP's search
The National Radon Proficiency Program's search finds its Certified Mitigation Specialists and Certified Measurement Professionals by area, by name, or by the 6-digit NRPP ID number a professional can give you.NRSB's search
The National Radon Safety Board's search finds a professional in your area, or confirms that a named professional is NRSB certified.The ID card
The programs usually issue a photo ID card showing the holder's qualifications and its expiry date. Ask to see it, and if in doubt, check with the body that issued it.
