ANSI/AARST MAH-2019

Scope: This standard specifies procedures, minimum requirements and general guidance for measuring radon concentrations in single-family residences. The protocol included in this standard of practice applies to testing these structures whether conducted for real estate or non-real-estate purposes. Purpose: 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.
