Abstract

Radioactive 82Sr/82Rb produced at Los Alamos National Laboratory is routinely used in generators for hospitals and medical laboratories to support cardiac imaging. The proper quantification of strontium radioisotopes in a sample is important to ensure quality and regulatory compliance. However, the quantification of the impurity 85Sr is difficult, because its primary gamma-ray at 514 keV interferes with the annihilation peak at 511 keV from 82Rb. Synthetic spectra were created as a quality test of several gamma-ray spectral analysis tools’ ability to resolve peaks in the 511/514 keV multiplet. The peak fitting results from the spectroscopy tools (RAYGUN, SPECANAL, GammaVision, UNISAMPO, and GAMANAL) are presented. These spectra can also be useful for other programs to test their annihilation peak analysis procedures.
