ANSI/AARST MS-QA-2019

This standard specifies minimum requirements for quality systems designed to quantify the concentration of radon-222 gas in air by qualified professionals (QPs) and laboratories, whose data are intended to be used to determine the need for, or success of mitigation. It is applicable to the wide variety of radon measurement devices used for indoor measurements, primarily in residential environments or buildings not associated with possession or handling or radioactive materials.
