ISO 11665-9-2016 Measurement of radioactivity in the environment -- Air: Radon-222 -- Part 9: Test methods for exh...:
(ISO 11665-9-2016),英文名为Measurement of radioactivity in the environment -- Air: Radon-222 -- Part 9: Test methods for exhalation rate of building materials。
它(ISO 11665-9-2016)是在2016-02-01发布,在2016-02-01开始实施。
被标准ISO/DIS 11665-9替代。
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.
