| 内容記述 | Using neutrons generated by d-Li reaction in the A-FNS, we analyzed radionuclidic purity of technetium-99m (99mTc). It is one of the most-used medical isotopes and the daughter radionuclide of molybdenum-99. The angular distribution of the neutrons by the d-Li reaction is isotropic, and the high energy neutrons around 14 MeV have strong angular dependence in the forward direction. The high energy neutrons produce various radioisotopes, because their energies are over threshold energies of nuclear reactions. We calculated neutron spectra in the A-FNS test cell by using the Monte Carlo transport code MCNP5 with the extension McDeLicious-11 and the nuclear data library FENDL-3.1d. Using the spectra, activation calculations were performed with the inventory calculation code FISPACT-2010. Ratios of the activity of 99mTc to that of other Tc radioisotopes were evaluated for the cooling time after the neutron irradiation. It was found that the purity met a medical demand after an adequate cooling time because of decrease due to the decay of radioisotopes. In addition, we clarified that the purity became higher after a chemical separation process of Tc. | |||||
