(Test Method)Standard Test Method for Radiochemical Determination of Uranium Isotopes in Urine by Alpha Spectrometry
Standard Test Method for Radiochemical Determination of Uranium Isotopes in Urine by Alpha Spectrometry
SIGNIFICANCE AND USE
5.1 This test method is used to detect possible exposures to uranium isotopes from occupational operations that may result in elimination via the urinary tract.
SCOPE
1.1 This test method is applicable to the determination of uranium in urine at levels of detection dependent on sample size, count time, detector background, and tracer yield. It is designed as a screening tool for detection of possible exposure of occupational workers.
1.2 This test method is designed for 50 mL of urine. This test method does not address the sampling protocol or sample preservation methods associated with its use.
1.3 Test Method C1844 offers an alternative method for the analysis of uranium in urine using ICP-MS detection.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in Section 9.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 A urine sample with U tracer solution added is wet-ashed with nitric acid and hydrogen peroxide to destroy organic
material. The uranium-bearing solution is converted to a hydrochloric acid medium. Uranium is absorbed on an anion exchange
column from a 9 M hydrochloric acid solution and eluted with 0.1 M hydrochloric acid solution. The separated uranium is prepared
for alpha spectrometric measurement either by electrodeposition onto a metal disk or coprecipitation with neodymium fluoride and
filtration onto a membrane filter.
