How Do Radioactive Materials Move?: Investigation of Radioactive Contamination in the Abukuma River Water System, Including Radioactive Contaminations of Soil, Air Radiation Dose, and Radioactive Contamination of a Bird Sanctuary (Research Papers,The 35th Symposium on Life Information Science)

Large quantities of radioactive materials have been released by the severe accident of March, 2011 at the Fukushima Daiichi Nuclear Power Plant and these materials have been deposited in the mountains and city areas. It is thought that these radioactive materials will finally be transferred to rivers unless land areas are decontaminated. We measured radiocesium concentrations of collected samples of river water soils and sediments in the basin of the Abukuma River water system. In particular, in City A city where some branches joined the Abukuma River., we investigated radioactive contamination of soil at about 300 places in the city and also air radiation dose at the same places for two years. Some results for City will be presented.Furthermore, we will report details of a GPS mapping of the air radiation dose in the forest of Fukushima City Kotori-no -mori Sanctuary where decontamination work has not been done yet, and we will influence on wildlife.
