1.1 This practice covers the preparation of separated actinide fractions for alpha spectrometry measurement.2 It is applicable to any of the actinides that can be dissolved in dilute ammonium sulfate solution. Examples of applicable actinide fractions would be an elution from an ion exchange / extraction chromatography separation or the final strip from a solvent extraction separation.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 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.


5.1 The determination of actinide elements by alpha spectrometry measurement is an essential part of many environmental research, bioassay, and monitoring programs. Alpha spectrometry measurements identify and quantify the alpha-emitting actinide elements. A variety of separation methods will typically precede the electrodeposition of a sample for alpha spectrometry measurements. In addition to the electrodeposition procedure presented in this practice, the scientific literature contains other procedures for actinide electrodeposition.

Note 1: An alternate method for mounting actinides for alpha spectrometry measurements by coprecipitation with neodymium fluoride is described in Practice C1163.
