Since the accidents at Fukushima Daiichi Nuclear Power Plant following the Tohoku Region Pacific Coast Earthquake on March 11th, 2011, Fukushima Environmental Safety Center has carried out research on natural mobilization of radionuclide (especially radiocesium) and future forecast from forest to water system and surrounding residential areas. The report summarizes the latest results that have been accumulated from each study field, of our agency together with the other related research organizations. The contents of the report is to be used as evidence-based information for the QA-styled pages in the website of JAEA Sector of Fukushima Research and Development at the time of next renewal.

Oral presentation

JAEA's challenges for Fukushima environmental recovery and relevant expectation for National Institute of Technology, Fukushima College

Miyahara, Kaname

no journal, , 

This presentation focuses on challenges for enhancing Fukushima environmental resilience to address the needs for better scientific and technological capabilities to assess, predict, and minimize the impact of radiological contamination and illustrate how to enhance the understanding of radiation and associated risks in the public. These long-term challenges need to involve young researches, therefore this presentation includes comments on relevant expectation for National Institute of Technology, Fukushima College.

Applications of radiocesium migration models to Fukushima environmental issues, 1; Overview

Kurikami, Hiroshi; Sakuma, Kazuyuki; Malins, A.; Yamada, Susumu; Machida, Masahiko

no journal, , 

Over recent years after the accident at the Fukushima Dai-ichi Nuclear Power Plant, we have developed and applied several numerical models covering various time- and spatial-scales to tackle environmental issues in Fukushima. Each issue requires selection of a suitable model. The issues we have tackled thus far include medium- to long-term prediction of the redistribution of radiocesium and changes of radiation dose rates in the air, estimation of discharge amounts of radiocesium from land to the ocean, understanding the behavior of radiocesium in rivers and lakes during heavy rainfall events, and evaluation of the effect of radocesium migration in the environment on forestry and fishery products. In this presentation, we give an overview of our modeling studies on environmental issues in Fukushima.
