The above report suggests that
1.) you get aboutwhen a 30 MeV electron beam hits a converter like Tungsten producing photons which hit a 5 cm thick Moly target. A 100 kW electron beam could make about 800 Ci/s of Mo-99.
2.) TheX-sect peaks at 160 mbarns when the photon energy is 15 MeV:(photofission of Mo-100 and U-238 have similar X-sections)
3.) single neutron emissions makes up about 60% of the photofission X-sectionX-sect is about 96 mbarns when photon energy is 15 MeV
4.) 40 million nuclear medicine procedures are performed each year, 20 million in the US. 80% of those procedures use Mo-99.
5.) The U.S. uses 6,000 - 7,000 6-day curies per week. 6-day curies = amount of Mo-99 left after 6 days ( half life is 66 hours < 3 days).14,000 curies per week.
Combining "1" and "5" means I need a 12 Watt dedicated electron machine to make Mo-99 each week for the U.S.?
If my technique for making Mo-99 uses 10, 50 micron thick foils of Mo-100 instead of a 5 cm thick target, then I need a 1200 Watt electron accelerator.
