New York is not on the list of states with radon credentialing programs that EPA's state contacts page publishes.

Before you hire

How to check a credential in New York

  1. New York's rule

    New York's radon program says the state does not license radon professionals, so ask for a national certification instead, and check it in the next two steps.

  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.
