The rule

Does Wyoming license radon professionals?

Wyoming's radon program page, checked on October 3, 2026, does not say whether the state licenses or certifies radon professionals. Ask the program before you hire.

Wyoming 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.

Before you hire

How to check a credential in Wyoming

  1. Wyoming's own list

    Start with Wyoming's radon program. Licensing is done by the state, and most states can give you a list of radon service providers working there.

  2. 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.

  3. 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.

  4. 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.

Hiring
