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

Mesurage de la radioactivité dans l'environnement — Air: radon 222 — Partie 4: Méthode de mesure intégrée pour la détermination de l'activité volumique moyenne du radon avec un prélèvement passif et une analyse en différé

Abstract / scope

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.
