Measurement of radioactivity in the environment — Air: Radon-222 — Part 9: Test methods for exhalation rate of building materials

95.99 Withdrawal of Standard May 14, 2019

General information

Current stage: 95.99 Effective date: May 14, 2019

Originator: ISO

Owner: ISO/TC 85/SC 2

Type: International Standard

ICS: 13.040.01 17.240

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.
