Protocol for Conducting Measurements of ANSI/AARST MAH 2019 Introduction Radon and Radon Decay Products in Homes Significant Changes in the 2019 Revision This standard of practice first published in 2005 and its most recent publication as an American National Standard in 2014 builds upon protocols developed by EPA relative to EPA’s “A Citizen’s Guide to Radon” and “Home Buyer’s and Seller’s Guide to Radon” publications. For 2019, improvements include: 1) Harmonization of structure and recent revisions from other ANSI/AARST measurement standards; 2) Improved clarity on the difference between guidance and mandatory requirements; 3) Companion Guidance with informational content that now includes guidance criteria for general inspection of installed mitigation systems ; and 4) Improved clarity for: - Test durations and locations, - How to handle test results that disagree, and - Professional requirements for qualification, onsite documentation and reporting.
