Standard Test Method for 238Pu Isotopic Abundance By Alpha Spectrometry
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 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 vulnerable to bias because of potential interference from any 238U isobar remaining after ion exchange.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
5.1 This test method is used when the determination of 238Pu isotopic abundance is required for plutonium samples.
