Several states require licensed professionals to follow specific protocols for testing of multifamily buildings. Two states have state-specific protocols while eight states have fully adopted the EPA-recognized radon standard of practice for testing multifamily buildings (see graphic below). This standard is identified as the “American National Standards Institute and American Association of Radon Scientist and Technologists (ANSI/AARST) Standard: Protocol for Conducting Measurements of Radon and Radon Decay Products in Multifamily Buildings (ANSI/AARST MAMF-Rev -2021)”. According to the protocol, testing locations include all ground-contact dwellings as defined within the MAMF-Rev-2021, large rooms or open areas (one every 2,000 square feet), as well as other ground contact (non-residential) rooms that are regularly occupiable, and 10% of upper floors.

National Certification Programs
National Radon Proficiency Program (NRPP) – The NRPP provides certification credentials for professional radon testers and mitigators. As an independent administrative program of the American Association of Radon Scientists and Technologists, Inc. (AARST), the NRPP holds the ISO 17024 ANSI accreditation and is governed by a Certification Council consisting of radon industry stakeholders who are responsible for credentialing policies and procedures.
National Radon Safety Board (NRSB) – The NRSB provides certification credentials for professional radon testers and mitigators. NRSB radon certification is formal recognition of professional excellence based on qualifications, high ethical standards, and continuing education in radon services.
