ISO 9696-2017 水质--总活性度--厚源试验方法 Water quality — Gross alpha activity — Test method using thick source

This document specifies a method for the determination of gross alpha activity in non-saline waters for alpha-emitting radionuclides which are not volatile up to 350°C.
The method is applicable to raw and potable waters.
The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter.
It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested.rd edition 2017-10 Water quality — Gross alpha activity — Test method using thick source Qualité de l'eau — Activité alpha globale — Méthode d'essai par source concentrée Reference number ISO 9696:2017(E) ？ ISO 2017 ISO 9696:2017(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2017, Published in Switzerland All rights reserved.
