1.1This test method covers the use of alpha spectrometry for determining the ²³⁸Pu isotopic abundance in plutonium samples. It is particularly useful for samples in which the ²³⁸Pu content is less than 1 % of the total plutonium content. For such samples, mass spectrometric results are vulnerable to bias because of potential interference from any ²³⁸U isobar remaining after ion exchange.

1.2The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3This 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.

1.4This 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.
