This test method is used to detect possible exposures to uranium isotopes from occupational operations.

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 efficiency, 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 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.
