This visit to the Safeguards Analytical Laboratory (SAL) concentrated on implementation quality-assurance (QA) and quality-control (QC) procedures for radiometry measurements. Multivariate statistical procedures to compare measurements from mass spectrometry and gamma-ray spectrometry were used to analyze 230 observations from seven sources of plutonium material. These comparisons showed that the results depended on the type of material and the method of estimating /sup 242/Pu. Procedures to estimate the pocket sensitivity for multicollector mass spectrometers were also investigated. A method was developed that estimated pocket sensitivity after adjusting for ion-density decays with time and mass differences. The QC charts implemented in May 1988 have already been useful for detecting data-entry errors, arithmetic errors, and an overheating amplifier on a mass spectrometer. 8 refs., 1 fig.
