摘要：

Measurement of the gamma ray energies and intensities of U-235 and Pa-234m enable those in Safeguards and Security to accurately identify and quantify amounts of U-235 and U-238. The most intense gamma ray lines in U-235, U-238, Th-234 and Pa-234 are all less then 290 keV. Without knowing the conditions of a measurement, we could measure these gamma ray lines and intensities inaccurately, leading to an incorrect identification of an isotope and its quantity. Two separate experiments were performed to measure the intensities of the gamma rays with energies greater then 290 keV in U-235 and Pa-234m. Higher energy gamma rays are attenuated less by their environment, making accurate identifications probable.
