Scope

WARNING: Personnel using this standard should have practical experience in laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This standard specifies the determination of ²³⁴ U/< The method of superscript 238>U, ²³⁰Th/²³²Th radioactivity ratio. This standard applies to the determination of ²³⁴U/²³⁸U, ²³⁰Th/²³²Th radioactivity ratios in 5L geological water samples. For the determination of ²³⁴U/²³⁸U and ²³⁰Th/²³²Th radioactivity ratios in 5L environmental water samples, reference can be made. Measuring range: Uranium: more than 1.23×10^-3Bq/L; Thorium: more than 1.23×10^-3Bq/L; ²³⁰Th/²³²Th: no greater than 15.
