Measurement of radioactivity in the environment -- Air -- Radon 220: Integrated measurement methods for the determination of the average activity concentration using passive solid-state nuclear track detectors
ISO 16641:2014 covers integrated measurement techniques for radon-220 with passive sampling only. It provides information on measuring the average activity concentration of radon-220 in the air, based on easy-to-use and low-cost passive sampling, and the conditions of use for the measuring devices.
ISO 16641:2014 covers samples taken without interruption over periods varying from a few months to one year.
