The rule

Does Kansas license radon professionals?

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

EPA's state contacts page lists Kansas among the states with radon credentialing programs. 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.

Listings for Kansas come from the list of licensed radon professionals that the Kansas Department of Health and Environment, Kansas Radon Program publishes, last read on October 4, 2026, and from businesses that confirm their own details through Radon411's claim process.

Before you hire

How to check a credential in Kansas

  1. Kansas's own list

    Start with the Kansas Department of Health and Environment, Kansas Radon Program. Licensing is done by the state, so its list or search says who may legally work in Kansas.

  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.
