There are three steps to become certified in the State of California:

1) Complete an approved training program.

2) Get certified by either one of the two certifying boards.

3) Submit a "Verification Form" along with a copy of your certificate to the Radon Program (there are no State fees).

(b)    Persons certified to provide radon services shall successfully complete and submit to the department proof of completion of the National Radon Measurement Proficiency Program of the National Environmental Health Association or the National Radon Safety Board Certified Radon Professional Program every two years after initial certification.

(c)    A copy of the current certificate of completion shall be submitted to the department at least 14 days prior to conducting radon services within the state. 

There are many programs that offer training programs acceptable to both the National Radon Safety Board (NRSB) and the National Environmental Health Association (NEHA).  If you are looking at a particular training program contact either of the certifying boards to confirm the acceptability of that  program.  It is not up to the State of California to accept or reject a particular training program.

Once you are certified by either NRSB or NEHA, complete the verification form (PDF)Opens in new window.and send it, along with a copy of your certificate, to the CDPH Indoor Radon Program, at the address below (see contact information).
