Scope

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

1.2 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.

Significance and Use

The determination of actinide elements by alpha spectrometry measurement is an essential part of many environmental research and monitoring programs. Alpha spectrometry measurements identify and quantify the alpha-emitting actinide elements. A variety of separation methods will typically preceed 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 Test Methods C 1163.
