Mo-99 Production
The above report suggests that
1.) you get about [math]\displaystyle{ 10^{12} \frac{neutrons}{s kW} }[/math] when a 30 MeV electron beam hits a converter like Tungsten producing photons which hit a 5 cm thick Moly target.
2.) The [math]\displaystyle{ (\gamma, n) }[/math] X-sect peaks at 160 mbarns when the photon energy is 15 MeV
