Mesurage de la radioactivité dans l'environnement — Air: Radon 222 — Partie 9: Méthode de détermination du flux d'exhalation des matériaux de construction

This edition has been replaced by ISO 11665-9:2019.

Abstract / scope

ISO 11665-9:2016 specifies a method for the determination of the free radon exhalation rate of a batch of mineral based building materials. The standard only refers to 222Rn exhalation determination using two test methods: Liquid Scintillation Counting (LSC) and gamma ray spectrometry (Annex A and Annex B)

The exhalation of thoron (220Rn) does not affect the test result when applying the determination methods described in this part of the standard.
