radioecological indexes of fallout measurements from the fukushima Nuclear Accident
Ecological Indicators, 2013Co-Authors: M Manolopoulou, S Stoulos, A Ioannidou, E Vagena, C PapastefanouAbstract:Abstract Fallout from the Fukushima Nuclear Accident has been monitored for about 1 month in Thessaloniki, Northern Greece. Three different radionuclides, one short-lived, one relatively long-lived and one long-lived fission product were identified in air, grass and milk samples. The 131 I, 137 Cs and 134 Cs activity concentrations in air reached 497, 145 and 126 μBq m −3 , respectively on 4 April, 2011. These radionuclides are of particular concern regarding their transfer from the environment to population through the ingestion pathways for the assessment of the Fukushima Accident consequences. Radioecological indexes (eco-indexes) of fallout measurements in the air–grass–cow-milk–man pathway for 131 I were determined, as they are related to radiological impact of the Fukushima derived radionuclides on the public and environment.

radiation measurements and radioecological aspects of fallout from the fukushima Nuclear Accident
Journal of Radioanalytical and Nuclear Chemistry, 2012Co-Authors: M Manolopoulou, S Stoulos, A Ioannidou, E Vagena, C PapastefanouAbstract:Fallout from the Fukushima Nuclear Accident has been monitored for about 1 month in Thessaloniki, Northern Greece. Three different radionuclides, one short-lived, one relatively long-lived and one long-lived fission product were identified in air, precipitation, soil, grass and milk samples. The 131I, 137Cs and 134Cs activity concentrations in air reached 497, 145 and 126 μBq m−3, respectively on 4 April, 2011. The external exposure dose rate to humans of the order of 14.4 pSv per day due to 137Cs deposited on the ground was very small compared to the normal background level. The accumulated dose equivalent to the adult thyroid from inhaled 131I varied from 0.4 to 3.5 nSv per day was insignificant and there was not any problem for the Greek population and no preventive measures were needed to be provided against the Nuclear Accident according to the Greek Atomic Energy Commission, the official agent of the Greek Government. Some special radioecological aspects in the air-grass-cow-milk-man pathway for 131I were particularly studied.

Importance of risk communication during and after a Nuclear Accident.
Integrated environmental assessment and management, 2011Co-Authors: Tanja PerkoAbstract:Past Nuclear Accidents highlight communication as one of the most important challenges in emergency management. In the early phase, communication increases awareness and understanding of protective actions and improves the population response. In the medium and long term, risk communication can facilitate the remediation process and the return to normal life. Mass media play a central role in risk communication. The recent Nuclear Accident in Japan, as expected, induced massive media coverage. Mass media were employed to communicate with the public during the contamination phase and they will play the same important role in the clean-up and recovery phase. However, media also have to fulfill the economic aspects of publishing or broadcasting, with the "bad news is good news" slogan being a well-known phenomenon in journalism. This paper addresses the main communication challenges and suggests possible risk communication approaches to adopt in the case of a Nuclear Accident. Integr. Environ. Assess. Manag. © 2011 SETAC.

the impact of the fukushima Nuclear Accident on european energy policy
Environmental Science & Policy, 2012Co-Authors: Bettina WittnebenAbstract:Abstract The disaster that struck the Fukushima Daiichi Nuclear plant in Japan has reignited the international debate on the future of Nuclear energy. Interestingly, the incident has been used to both justify Nuclear power generation and reconsider past decisions made on established or planned Nuclear power sites. Geographically removed from the radioactive fallout, Europe's response to the massive Nuclear Accident differed greatly among the member states. The UK and Germany stand out as examples of the wide spread of policy response to the Fukushima Daiichi Nuclear Accident. In the UK, policy makers remained firm on their decision to increase Nuclear power generation in the near future, whereas in Germany, the federal government decided to at least temporarily shut down the old generation of Nuclear reactors and re-examine the safety of all national Nuclear power facilities. Furthermore, a regional voter backlash, fuelled by resentment of the Merkel government's previous commitment to Nuclear power, dealt a serious blow to the ruling coalition parties. How can national policy responses to the same event be so divergent in two European countries? This article attempts to answer this question in five arguments. I argue that in contrast to the UK, the German public faced imminent elections, stronger media reporting, increasing trust in renewable technologies, a history of Nuclear resistance and a feeling of close cultural proximity to the Japanese.

Radioactive source terms for the Fukushima Nuclear Accident
Science China Earth Sciences, 2015Co-Authors: Wuhui Lin, Liqi Chen, Zhi Zeng, Shi ZengAbstract:A large amount of radioactivity was released into the environment after the Fukushima Nuclear Accident (FNA) in Japan in 2011. This radioactivity had a significant impact on the global environment, and there was much public concern about its effects. The subsequent assessment of the FNA and the environmental remediation required are proving to be long and complicated tasks. The assessments are based on the radioactive source terms for the FNA, which determine the level of damage caused by the Nuclear Accident. We investigated the radioactive source terms from three aspects: the amount and composition of the radionuclides; the activity and atomic ratio of the radionuclides; and comparison with other historical events. The total amount of radioactivity, excluding the radioactive noble gases (85Kr and 133Xe), released by the FNA was about 10% of that released by the Chernobyl Nuclear Accident in 1986 and

Radioactivity impacts of the Fukushima Nuclear Accident on the atmosphere
Atmospheric Environment, 2015Co-Authors: Wuhui Lin, Liqi Chen, Zhi Zeng, Jintai Lin, Shi ZengAbstract:Abstract The Fukushima Nuclear Accident (FNA) resulted in a large amount of radionuclides released into the atmosphere and dispersed globally, which has greatly raised public concerns. The state of the art for source terms of 19 kinds of radionuclides derived from the FNA was comprehensively collected and compared with levels of the global fallout and the Chernobyl Nuclear Accident (CNA). The atmospheric impacts of the FNA were evaluated from three aspects including radioactive baseline of the atmosphere, the concentration limits in standards and radiological protection. The FNA should not impose significant radiological risk on the public members in the countries excluding Japan. A conceptual scheme of Fukushima-derived radionuclides with physical and physicochemical insights on different temporal–spatial timescales was discussed and illustrated to understand their fates in the atmosphere.
