National Associations 

The AARST Consortium on National Radon Standards is a non-profit organization owned by AARST. The consortium serves as the forum for development, maintenance and publication of national consensus standards, which include processes, procedures and quality assurance systems to ensure standardized approaches for measurement and mitigation in both existing and new buildings. Hundreds of volunteer members representing key stakeholder groups, including analytical laboratories, federal and state regulators, radon measurement and mitigation contractors, product manufacturers, training organizations, scientists and academia, and environmental consultants, have developed and continue to maintain standards through participation on multiple committees.
