Measurement of radioactivity in the environment — Air: radon-222 — Part 4: Integrated measurement method for determining average activity concentration using passive sampling and delayed analysis (ISO 11665-4:2021)
This document describes radon-222 integrated measurement techniques with passive sampling. Itgives indications for determining the average activity concentration of the radon-222 in the air frommeasurements based on easy-to-use and low-cost passive sampling, and the conditions of use for thesensors.This document covers samples taken without interruption over periods varying from a few days toone year.This measurement method is applicable to air samples with radon activity concentrations greaterthan 5 Bq/ m3.
