The New Jersey Department of Environmental Protection and the Commission on Radiation Protection have repealed the existing radon certification program and adopted new rules applicable to individuals and businesses that test for or mitigate radon. The new provisions take effect on December 6, 2022.

  • The ANSI-AARST measurement and mitigation standards (MAH, MAMF, MALB, SGM-SF, RMS-LB, and RMS-LB) have been adopted.
  • The Department established five categories of certification and an affiliate program that allows individuals to associate with one or more certified businesses to conduct radon testing or mitigation.
    • The certifications are radon measurement specialist, radon measurement technician, radon mitigation specialist, radon measurement business, and radon mitigation business.
  • Currently certified persons and businesses must complete renewal applications by October 3, 2022.
  • Individuals who perform measurement or mitigation work in multifamily or large buildings are required to complete eight hours of training in multifamily or large buildings (or both if working in both).
  • The New Jersey-specific exam will be phased out; applicants will be required to pass exams administered by the National Radon Proficiency Program or other organization that the Department determines administers a substantively equivalent examination. The Department will provide a list of approved organizations on its website,
