Analysis of the relationship between ambient dose, ambient dose equivalent and effective dose in operational neutron spectra

Endo, Akira

This study examines the relationship between ambient dose , ambient dose equivalent , and effective dose for external neutron irradiation over 163 operational spectra from different workplaces. The results show that provides a reasonable estimate with a controlled margin, even if overestimated, to assess effective dose compared with , which can lead to a significant overestimation or underestimation of effective dose depending on the neutron spectra. The results highlight the limitations of and the superiority of in estimating effective dose according to the requirements of the operational quantity, especially in environments with high-energy neutrons.
