    Start with the Iowa Department of Health and Human Services, Bureau of Radiological Health. Licensing is done by the state, so its list or search says who may legally work in Iowa.

  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
