@misc{oai:repo.qst.go.jp:00076012, author = {Aono, Tatsuo and Aono, Tatsuo}, month = {May}, note = {A nuclear accident of the Fukushima Daiichi Nuclear Power Station (FDNPS) had been caused by the tsunami after the Great East Japan Earthquake in March 2011, and the huge amounts of radionuclides was dispersed around Fukushima immediately [1]. It is important that the activity concentrations of radionuclide have been continuously monitored in the territorial and marine environment due to understand the dispersion and behavior of radionuclide after the FDNPS accident. Furthermore, the effects of released radionuclides on agricultural, forest and fishery products after the FDNPS accidents have been discussed with the temporal and spatial variations of activity concentrations of radionuclide in the environment. After this accident, Nuclear Emergency Response Headquarters in Japan started the use of the provisional regulation value in food promptly (March 17, 2011-March, 2012). This concept of the limit for food and water is less than 5mSv/yr. However, it was necessary to carefully consider external and internal exposure due to the FDNPS is located in neighborhood. Based on the concept of 1mSv/yr for food and drinking water, new standard value in food (the limit of general food: 100 Bq-Cs/kg) was enforced from April1, 2012. The concentrations of radiocaesium (R-Cs) in seawater are almost same levels before the accidents except the near site of FDNPS, and these in fish generally decreased, and radiation doses from foods intake are negligible [2]. However, high concentrations of R-Cs are kept to some specific products as food as the result of nutrient cycle, accumulation, translocation and food chain. In this presentation, we would like to talk about the estimation of internal dose from food intake and the survey of consumer awareness for food in Japan with the monitoring of R-Cs in the environment after the FDNPS., 3rd International Conference “RADON IN THE ENVIRONMENT2019”}, title = {Radionuclide contamination in food and estimation of radiation doses from food intake since the Fukushima Nuclear Power Station Accident}, year = {2019} }
