THE RADON REPORTER | 17 STANDARDS ANSI/AARST Standards Revisions - Technical Bulletins As a result of the hard work of the leadership and committees of the AARST Consortium on National Standards, American Association of Radon Scientists and Technologists (AARST) last June released the 2023 versions of eight ANSI/AARST Standards. These standards have been revised by their respective all-volunteer committees to, for example, include changes recommended by subject matter experts, make edits necessary to increase clarity, and achieve harmonization across standards. Below are the technical bulletins for two of the updated standards. Through this work, the AARST Consortium continues to lead the way in protecting public health and safety. For an extended look at the update of these two standards go to: MA-MFLB 2023 – Technical Bulletin & Substantive Changes and SGM 2023-Technical Bulletin & Substantive Changes. MA-MFLB 2023 Protocol for Conducting Measurements of Radon and Radon Decay Products in Multifamily, School, Commercial, and Mixed-Use Buildings The MA-MFLB 2023 standard is a comprehensive consolidation and update of the previous MAMF 2017 and MALB 2014 standards. This updated standard aims to streamline the protocols for conducting radon measurements in various building types, ensuring a consistent approach across different environments. Key revisions include: • Harmonization and Consolidation: Merging the MAMF and MALB standards to create a unified protocol. • Enhanced Clarity: Improved editorial clarity and integration of residential and commercial space requirements. • Detailed Test Procedures: Updated sections on test conditions, locations, procedures, and reporting to ensure accuracy and compliance. For more detailed information on the revisions and their implications, you can view the full technical bulletin and substantive changes here: MA-MFLB 2023 Technical Bulletin and Substantive Changes. SGM-MFLB and SGMSF: Soil Gas Mitigation Standards for Existing Homes and Large Buildings The SGM 2023 standards encompass the revised soil gas mitigation protocols for both existing homes and larger buildings such as multifamily units, schools, commercial, and mixed-use buildings. This update consolidates and harmonizes the previous RMS-MF 2018 and RMSLB 2018 standards into a singular, cohesive document. Highlights of the revisions include: • Consolidation and Harmonization: Combining RMSMF and RMS-LB into a single standard, with a focus on consistent application across different building types. • Quality Control and Compliance: New requirements for diagnostic inspections, quality control oversight, and post-mitigation evaluations. • Health and Safety: A rewritten section focusing on a comprehensive safety management plan, including safety training.
