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
