Title
Standard Test Method for 238Pu Isotopic Abundance by Alpha Spectrometry

ASTM International

Publication Date:
Jun 10, 2001

Scope:

This 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 less reliable than those from alpha spectrometry because of interference from any ²³⁸U isobar remaining after ion exchange.

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.

Keywords:
