1.1This test method describes a solid phase extraction (SPE) procedure to separate 99Tc from environmental water (non-process-related or effluent water samples). Technetium-99 beta activity is measured by liquid scintillation spectrometry.
1.2This test method is designed to measure 99Tc in the range of approximately 0.037 Bq/L (1.0 pCi/L) or greater for a one litre sample.
1.3This test method has been used successfully with tap water. It is the user’s responsibility to ensure the validity of this test method for samples larger than 1 L and for waters of untested matrices.
1.4Technetium-99 alternatively can be determined in water samples using Practice D8026.
1.5The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered standard.
1.6This 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.
