Radon Measurements Systems Quality Assurance
This standard of practice specifies minimum requirements for quality systems designed to quantify the concentration of 222 Rn gas in air by qualified professionals (QPs) and laboratories, whose data are intended to be used to determine the need for, or success of, radon mitigation.
Updates for 2023 include clarity on warning and control limits for less than 2 pCi/L (75 Bq/m 3 ) and harmonization with ANSI/AARST MS-PC on several definitions.
