ISO 11483: 2005 describes three simple and fast procedures to prepare plutonium sources and a procedure to measure the activity ratio of 238Pu to (239Pu + 240Pu) by alpha spectrometry. The alpha spectrometry method is used for the determination of isotopic abundance of 238Pu in combination with mass spectrometry and eliminates the possible interferences of 238U in the latter method. It applies to the analysis of purified solutions of plutonium in 2 mol/l to 4 mol/l nitric acid containing 50 micrograms to 200 micrograms of plutonium per millilitre, as may result from the chemical treatment and purification preceding plutonium isotopic analysis by mass spectrometry.
Abstract
Overview
ISO 11483:2005 - "Nuclear fuel technology - Preparation of plutonium sources and determination of 238Pu/239Pu isotope ratio by alpha spectrometry" - specifies fast, reproducible procedures for preparing plutonium alpha sources and for measuring the 238Pu/(239Pu + 240Pu) activity ratio by alpha spectrometry. The method is intended to complement mass spectrometry for plutonium isotopic analysis and helps eliminate potential 238U interferences in mass-based measurements. It applies to purified plutonium solutions in 2–4 mol·L−1 nitric acid with 50–200 µg Pu·mL−1, and to materials free from americium or containing
