AbstractThis dataset consists of 11509 records of 134Cs and 11509 records of 137Cs activity concentrations in fish samples collected within 20 km and in the port of FNPP1 measure by TEPCO and published at TEPCO web site. One of the authors, Prof. Michio AOYAMA, obtained written permission from TEPCO to publish all of the TEPCO monitoring data in TEPCO web site at ERAN database site of Univ. of Tsukuba. The permission was dated on 22 March 2021. A part of the data in this dataset was already published as a supplementary datasets of two scientific articles by Wada et al., (2016) at 10.1016/j.jenvrad.2016.06.028 and Wada et al., (2019) at 10.1016/j.jenvrad.2019.04.006. Original pdf files in a TEPCO web site of this dataset are also provided with formatted data.
