The California Health and Safety Code (HSC) is the prevailing regulatory statute that applies to the control of radon in California including but not limited to requirements for performing radon measurement, mitigation, and laboratory analysis. HSC Section 106780 requires that no person may provide radon services for the general public, or represent or advertise that he or she may provide radon services unless that person meets the provisions of HSC, Section 106780, which includes successfully completing the National Radon Proficiency Program (NRPP) or the National Radon Safety Board Certified Radon Professional Program (NRSB). Both programs require their certified individuals to follow the American National Standards Institute, American Association for Radon Scientists and Technologists (ANSI-AARST)ā standards, which includes the requirements for 100% ground contact testing for multifamily housing and testing 10% upper floor units. āVisit the NRPP and NRSB websites to view information regarding their certification requirements. āāāā
