1.1 This test method describes a solid phase extraction (SPE) procedure to separate 99<\/sup> Tc from environmental water samples (that is, non-process and effluent waters). Technetium-99 beta activity is measured by liquid scintillation spectrometry.<\/p>\n

1.2 This test method is designed to measure 99<\/sup> Tc in the range of approximately 0.037 Bq\/L (1.0 pCi\/L) or greater for a one litre sample.<\/p>\n

1.3 The values stated in SI units are to be regarded as standard. Values given in parentheses are provided for information purposes only.<\/p>\n

1.4 This 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.<\/p>\n

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 and health practices and determine the applicability of regulatory limitations prior to use.<\/i> For specific hazard statements, see Section 9.<\/p>\n
