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 Ingestion-build-276583 BS EN ISO 14644-6:2007 replaces1 Scope This International Standard 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. This International Standard covers samples taken without interruption over periods varying from a few months to one year. This type of
