Abstract
Innovative accelerator-based production routes for 99Mo (and 99mTc) have been studied, comparing the 100Mo(p,x)99Mo,99mTc and 96Zr(α,n)99Mo reactions, for which a new set of measurement has been made. Theoretical and experimental cross sections have been analysed and used to calculate 99Mo production yields and specific activity (SA), considering fully enriched and commercially available target materials. Results show that the low SA resulting from the p-based route forces the use of alternative generator systems, while the α-based reaction provides very high SA 99Mo but much lower yield. Benefits and drawbacks of direct 99mTc production via the 100Mo(p,2p) reaction are also discussed.
