Temperature and time dependence on extraction of Molybdenum-99 hot atoms from neutron-irradiated β-molybdenum trioxide particles into water.

This study presents a novel perspective by examining the influence of temperature and heating time on the extraction of Mo into water, contributing to a better understanding of its extraction kinetics. β-MoO particles were synthesized thermal evaporation and subsequently characterized using X-ray diffraction and transmission electron microscopy. These particles were then neutron-irradiated at the Kyoto University Research Reactor facility, after which the activity of the Mo in the particles was analyzed by a high-purity germanium semiconductor detector.

β-MoO Whiskers in Mo/Tc Radioisotope Production and Mo/Tc Extraction Using Hot Atoms.

β-MoO whiskers prepared by a thermal evaporation method and α-MoO particles were irradiated in a nuclear reactor to produce Mo/Tc radioisotopes via neutron capture. The irradiated targets were then dispersed in water to extract the Mo/Tc isotopes. Of the Mo formed in the β-MoO whiskers, 64.
