Times Cited Count：5 Percentile：46.12(Instruments & Instrumentation)Methodologies to derive cross section data from spectrum integrated reaction rates were studied. The Westcott convention and some of its approximations were considered. The accuracy of the results strongly depends on the assumptions that are made about the neutron energy distribution, which is mostly parameterised as a sum of a thermal and an epi-thermal component. Resonance integrals derived from such data can be strongly biased. When the energy dependence of the cross section is known and information about the neutron energy distribution is available, a method to correct for a bias on the cross section at thermal energy is proposed. Reactor activation measurements to determine the thermal Am(n, 
) cross section reported in the literature were reviewed, where the results were corrected to account for possible biases. These data combined with results of time-of-flight measurements give a capture cross section 720 (14) b for Am(n, ) at thermal energy.

Am is generated by beta-decay of Pu. In the case of treating MOX, it is important for shielding about 60keV gamma-ray emitted by Am. Also getting dose rate data of MOX containing Am is valuable. In this work, we measured gamma-ray dose rate from MOX containing Am by changing thickness of shielding materials and range between MOX and measuring instruments. Also we confirmed that calculating analysis is useful for evaluation of shielding material's performance.

In this research, purpose is getting gamma dose rate from MOX and PuO
containing Americium and evaluating exposure dose by calculation code. One of reasons of difference between measurement value and calculation value is scattering ray from inside of globe box panel because MOX is handled inside of globe box. Therefore, we improve measuring method (changing MOX position, applying shadow shield method) and get new data which difference between measurement value and calculation value (using ANISN) is smaller than before. Furthermore, we confirm that it can be available to apply PHITS for evaluating exposure dose.
