The observation of the 239 keV gamma line from 232U decay in high-enriched uranium (HEU) samples prompted us to utilize 232U (with main gamma energies of its daughters at 239, 583, 763, and 860 keV) as a mediator isotope for performing relative (intr

Publikováno v: Nuclear Science and Technology. 4:1-6

In this work the non - destructive gamma spectroscopic method for determination of uranium enrichment is presented. In order to determine the uranium enrichment the activity ratios of 234U/235U and 238U/235Uwere measured. The activity ratios234U/235U

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 305:40-44

In order to support and refine in-field NDA methods developed for the assay of PuBe sources the heat power of a set of such sources is measured by a heat-flow calorimeter. The Pu isotopic composition of the sources was determined by gamma spectrometr
