摘要：
We discuss the possibility of producing Mo-99 radioisotope using an electron beam accelerated in the linac injector of the SOLARIS synchrotron. Mo-99 with a half-life of 65.94 h, is a parent of the medically important radioisotope Tc-99m(T-1/2 = 6 h). In our study Mo-99 was produced from Mo-nat(gamma, x) reaction using Bremsstrahlung gamma radiation generated by 60, 100 and 200 MeV electron beams hitting a tungsten radiator located in front of the target. The activity of Mo-99 was analysed by off-line. spectroscopy using a HPGe detector. Auxiliary Monte-Carlo simulations were performed to determine the flux and energy distribution of the Bremsstrahlung photons. The activity thus obtained is high enough to consider the feasibility for commercial purposes of the production of Mo-99 through photo-nuclear reactions. Apart from the reaction of interest, the activity of other long-lived radioactive impurities produced from Mo-nat(gamma, x) reactions were determined.
