DESCRIPTION
BS ISO 11665-4:2021
This standard BS ISO 11665-4:2021 Measurement of radioactivity in the environment. Air: radon-222 is classified in these ICS categories:
- 17.240 Radiation measurements
- 13.040.01 Air quality in general
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.
