The American Association of Radon Scientists & Technologists (AARST) administers the National Radon Proficiency Program (NRPP), an ANSI National Accreditation Board accredited certification body under ISO/IEC 17024 standards. The private company is based in Hendersonville. NRPP certifies radon professionals, including measurement professionals, mitigation specialists, technicians, and inspectors, ensuring they meet competency, ethical, and industry standards for radon testing and mitigation. Certification requires passing standardized exams, adherence to ANSI/AARST consensus standards, and biennial renewal through continuing education. The organization maintains an official list of approved radon measurement devices and laboratories, provides training courses, study materials, consumer resources, and supports professionals with a certification portal and directory. AARST develops and updates national consensus standards for radon measurement and mitigation across various building types, which are recommended by the EPA and adopted to protect public health from radon exposure.
