Influence of enriched 100Mo on Mo reaction yields

Abstract

Abstract In accelerator-driven 99Mo/99mTc production, the 100Mo enrichment level should be chosen carefully as it greatly affects the yields of the involved Mo reactions. To facilitate selecting the 100Mo enrichment level, we defined a figure of merit called density change coefficient and developed its calculation program. Density change coefficients calculated for nine commercial enriched 100Mo products are presented and their use in selecting the 100Mo enrichment level is discussed.
