Abstract

Monthly precipitation samples have been collected at Toki, Japan, from November 2013 to March 2017. In this report, selected data were analysed to identify the regional hydrogen and oxygen isotope compositions. Tritium (³H) concentration in the precipitation ranged from 0.10 to 0.61 Bq L^-1 and higher ³H concentrations were observed in spring rather than in other seasons. This range was similar to values reported in Chiba City, Japan. ³H concentration and the ratio d-excess, and δD values were roughly clustered according to each separate season. These regional hydrogen and oxygen isotope compositions will be used for environmental assessments of effects of the deuterium plasma experiments of the large fusion test device.
