Standard Test Method for Uranium in Drinking Water by High-Resolution Alpha-Liquid-Scintillation Spectrometry
N D6239
Annotation
This test method covers determining the total soluble uranium activity in drinking water in the range of 0.037 Bq/L (1 pCi/L) or greater by selective solvent extraction and high-resolution alpha-liquid-scintillation spectrometry. The energy resolution obtainable with this technique also allows estimation of the 238U to 234U activity ratio.
This test method was tested successfully with reagent water and drinking water. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.
The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9.

Метод стандартной пробы для урана в питьевой воде спектрометрией Жидкого Сверкания альфа-с высоким разрешением
Этот метод тестирования покрывает определение общего разрешимого действия урана в питьевой воде в диапазоне 0.037 Bq/L (1 pCi/L) или больше выборочной жидкостной экстракцией и спектрометрией альфа-жидкой сцинтилляции с высоким разрешением. Энергетическое разрешение, доступное с этим методом также, позволяет оценку 238U к 234U показатель активности.
