The radiation dose of Fukushima nuclear accident and its effect for health of public members / 中国医学装备

ABSTRACT

Objective:To investigate the radiation dose and its impact for human health after the Fukushima nuclear accident in Japan.Methods: The Fukushima nuclear accident caused by the Richter 9 earthquake of the east sea of Miyagi prefecture in Japan and huge tsunami was analyzed. And the detection results of the radiation dose from the nuclear accident that was named 7th grade event was evaluated whether existed effect for human health.Results: The radiation dose rate of the environment after this nuclear accident from the first nuclear power plant of Fukushima was increased, and the radioactive ranges of134Cs and137Cs mainly came from the leak of nuclear power plant were 100~500PBq and 6~20PBq, respectively. At the same time, the radioactive contaminations were found existed in water and foods, and they had posed a threat for marine organism.Conclusion: The detection result of nuclear accident of Fukushima has higher value for the evaluation of after-effect about human health, and the effects of Fukushima nuclear accident and its impact for life, property and ecological environment are worth pondering.
