Abstract:
In this study, a Monte Carlo code was used to simulate a proton beam flux to calculate the (94m)Tc production yield from the (94)Mo(p,n)(94m)Tc reaction. An experimental yield of 3.465 GBq/μAh was measured for 48 min of irradiation at 1μA. An estimated value of 3.048 GBq/μAh was calculated for the yield produced based on the MCNPX proton flux in the same situation. These results demonstrate the usefulness and precision of MCNPX as a tool to design targets for the production of PET radionuclides. The yield of isotopic impurities from the (94)Mo(p,xn)(94g, 93m, 93g)Tc reactions was also calculated by the MCNPX code.
