内容記述 | Tellurium-132 (Te-132, half-life: 3.2 d) would be considered as a contributor to the radiation dose from the Fukushima Daiichi Nuclear Power Plant (FDNPP) during the early stages of accident, that is, in March 2011. The Nuclear and Industrial Safety Agency (2011) estimated total amount of radionuclides discharged to the air from the FDNPP, and the most released radionuclide was non-reactive Xe-133 (1.1x10^19 Bq) followed by I-131 (1.6x10^17 Bq) and Te-132 (8.8x10^16 Bq). Indeed, high-volume air sampling results in March 2011 carried out by JAEA in Takasaki (2012) and KEK in Tsukuba (2012) showed that observed Te-132 activity was as high as that of I-131 in both institutes. However, there is far less available data for Te-132 in soil because of the nuclide's short half-life. Thus, its distribution has not yet been adequately described. The Ministry of Education, Culture, Sports, Science and Technology (MEXT) has reported Te-129m (half-life: 33.6 d) distribution in soils of Fukushima, but presents no data for Te-132 because the soil sampling (May-June 2011) was too late to detect it. In this study, therefore several reliable data sets were compiled to estimate Te-132 distribution in the soils of Fukushima Prefecture in March 2011. | |||||
