Measured bremsstrahlung photonuclear production of 99Mo (99mTc) with 34 MeV to 1.7 GeV electrons

Development and validation of an analytical model of isotope production by bremsstrahlung radiation

An analytical method is used to describe isotope production at an electron accelerator. The key characteristics that determine the total target activity and its distribution have been established. The expressions for the reaction yield depend explicitly on the irradiation regime and parameters of the giant dipole resonance. The model predictions for the bremsstrahlung spectrum and yield of the reference reactions are in good agreement with the results of simulation and experiment.

Computational simulation of natUO2, 232ThO2 and U3O8-Al pills to estimate (p,fission) 99Mo yield in the modeled targets irradiated by CYCLONE30 accelerator

⁹⁹Mo is important for both therapy and imaging purposes. Accelerator and reactor-based procedures are applied to produce it. Newly proton-fission method has been taken in attention by some research centers. In the present work, computationally investigation of the ⁹⁹Mo yield in different fissionable targets irradiated by proton was aimed. The results showed UO₂ pill target could be efficiently used to produce 11.12Ci/g-U saturation yield of ⁹⁹Mo using 25MeV proton irradiation of the optimized-dimension target with 70µA current.
