A national consensus standard is available for every building type:ĪNSI/AARST MAH-2023 Protocol for Conducting Measurements of Radon and Radon Decay Products in Homes The consortium is an ANSI-approved standards developer, which means standards are developed and maintained through ANSI’s established consensus process to ensure openness, balance and due process through the following items:Ĭurrent ANSI/AARST National Consensus StandardsĪNSI/AARST national consensus standards are utilized by numerous federal and state agencies, such as the Department of Housing and Urban Development (HUD) and the Environmental Protection Agency (EPA). 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.Īccreditation by the American National Standards Institute (ANSI) 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. ![]() The AARST Consortium on National Radon Standards is a non-profit organization owned by AARST. The AARST Consortium on National Radon Standards For more information, please visit “ EPA Guidance on the Use of Voluntary Consensus Standards for State Indoor Radon Grant Recipients.” Federal participation in the development and use of VCS is governed by the National Technology Transfer and Advancement Act (1995), and Circular A-119 (2016, 1998) issued by the Office of Management and Budget, Executive Office of the President. Environmental Protection Agency (EPA) has been actively participating in the radon industry-led ANSI/AARST voluntary consensus-based standards (VCS) process since 2012. Whether the source of radon is through soil or water, or by emanation from building materials, preventing radon exposure to building occupants is one of the most important environmental health challenges we face today.ĮPA Recommends States Reference ANSI/AARST Radon Standards Publication: © 2019-2023 CERN (License: CC-BY-3.The impact of occupant exposure to radon in buildings is an important public protection issue that requires standardized approaches to measurement and mitigation, and long-term stewardship to confirm concentrations in buildings remain below the EPA Action Level. This paper describes the RaDoM2, its improved performance compared to RaDoM, the cloud and user interface, tests in a radon chamber and on-the-field measurements. This solution has allowed the optimization of the geometry, the pump flow rate and the associated electronics, improving the performance of RaDoM and substantially reducing its manufacturing costs. In this improved version, RaDoM2, the Timepix has been replaced by a silicon pin diode. ![]() The first version, which used the Timepix hybrid pixel detector, a system of filters and a pump, correctly assessed the effective dose in situations where the environmental conditions are characterized by a standard equilibrium factor, but showed low efficiency for low radon concentrations and in clean air environments. RaDoM is an active detector able to directly estimate the effective dose due to the radon progeny. Romano, S (CERN Barcelona, Polytechnic U.) Caresana, M (Milan, Polytech.) Curioni, A (CERN) Silari, M (CERN)Ī new dosimeter for radon progeny called RaDoM (Radon Dose Monitor) was recently developed at CERN.
