1.1 This practice covers the separation and preconcentration of neptunium-237 ( 237<\/sup> Np), thorium-232 ( 232<\/sup> Th), uranium-235 ( 235<\/sup> U) and uranium-238 ( 238<\/sup> U) from urine followed by quantitation using ICP-MS.<\/p>\n

1.2 This practice can be used to support routine bioassay programs. The minimum detectable concentrations (MDC) for this method, taking the preconcentration factor into account, are approximately 1E-2Bq for 237<\/sup> Np (0.38ng), 2E-6Bq for 232<\/sup> Th (0.50ng), 4E-5Bq for 235<\/sup> U (0.50ng) and 6E-6Bq for 238<\/sup> U (0.48ng).<\/p>\n

1.3 This standard does not purport to address all of the safety problems, 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.<\/i><\/p>\n
