英文名称：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

发布日期：2021-03

标准范围

This document describes radon-222 integrated measurement techniques with passive sampling. It 
gives indications for determining the average activity concentration of the radon-222 in the air from 
measurements based on easy-to-use and low-cost passive sampling, and the conditions of use for the 
sensors.
This document covers samples taken without interruption over periods varying from a few days to 
one year.
This measurement method is applicable to air samples with radon activity concentrations greater 
than 5 Bq/m³ .
