The disposal of radioactive waste from the research facility need to calculate from the radioactivity concentration that based on variously nuclear fuels and materials. In Japan Atomic Energy Agency Oarai Research and Development Institute, the study on considering disposal is being advanced among the facilities which generate radioactive waste as well as the facilities which process radioactive waste. This report summarizes a study result in FY2020 about the evaluation method to determine the radioactivity concentration in radioactive waste on Oarai Research and Development Institute.

We have studied the magnon density of state in yttrium iron garnet ranging from 0.02 meV to 20 meV by using spectrometers, DNA, AMATERAS, and 4SEASONS, at J-PARC/MLF. The E-dependence is well reproduced by a simple square-root function in this energy range.
