| 内容記述 | Tellurium-132 (132Te, half-life: 3.2 d) has been assessed as the radionuclide with the third largest release from the Fukushima Daiichi Nuclear Power Plant (FDNPP) in March 2011; thus it would have made some dose contribution during the early stage of the reactor failures. The available data for 132Te are, however, limited. In this study, available reported values of other isotopes of Te were compiled to estimate 132Te concentration (in MBq m-2). It was found that 132Te and 129mTe (half-life: 33.6 d) concentrations were well correlated (R=0.99, p<0.001) by t-test. Thus 132Te concentrations on March 11, 2011 were estimated from 129mTe using the concentration conversion factor (132Te /129mTe) of 14.5. It was also found that since deposited 129mTe was well retained in the soil, the data collected in March-May of 2011 were applicable to 132Te estimation. It was possible to obtain the first 132Te concentration contour map for the eastern part of Fukushima Prefecture, including data from within the 20-km exclusion zone around the FDNPP, using these newly available estimated 132Te data sets. | |||||
