摘要：
The majority of practical radioactive materials decay by modes that include gamma-ray emission. For questions of "how much" or "how pure," one must know the absolute intensities of the major radiations. We are using liquid scintillation counting (LSC) to measurements of disintegration rates, coupled with gamma-ray spectroscopy to measure absolute gamma-ray emission probabilities. Described is a study of the Th-227 chain yielding absolute gamma-ray intensities with similar to 0.5% accuracy and information on LSC efficiencies.
