ANSI/AARST MAH-2019Protocol for Conducting Measurements of Radon and Radon Decay Products in Homes
This standard of practice specifies minimum requirements and general guidance for measuring radon concentrations in single-family residences. This standard applies to testing structures whether conducted for real estate or non-real-estate purposes. The purpose of test protocols is to consistently produce, to the extent possible, reliable and repeatable radon measurements. Radon measurements are conducted to determine if radon mitigation is necessary in order to protect current and future occupants.
