The Arizona Radiation Regulatory Agency (ARRA) does not regulate or certify radon testers or mitigation specialists. It is recommended that people employ qualified professional contractor who knows and uses EPA protocols to test or mitigate homes. Certification and training programs for radon professionals are available from EPA recommended provides, such as NRPP and NRSB.
The Radon Measurement Course has been approved by both NRSB and NRPP for initial certification. If you are interested in expanding your business to do radon testing, you can begin by taking the PHII Radon Measurement course. When you have completed the course, you will receive information on how to register for the NRPP or NRSB exam. Both organizations require that you complete an approved course, pass their certification exam, and maintain your certification with continuing education.
Note: NRSB has also approved PHII's Radon Measurement Course for 16 Hours of Continuing Education.
