Abstract :
The gamma ray emission probability is one of the most important characteristics used in quantifying radionuclides. This article describes in detail the principles and processes involved in the determination of the 135Xe gamma ray emission probability. Gaseous samples of 135Xe were generated by irradiating enriched 134Xe with a thermal neutron flux. The principal gamma ray emission probability of 135Xe was then determined to be 0.896±0.016 (k=1) by measuring the absolute activity using length-compensated internal gas proportional counters and γ-ray intensity using a high-purity germanium (HPGe) detector.
