福岛核事故后放射性扩散的灰色关联度分析
nalysis of Radiation Diffusion of Fukushima Nuclear Accident Based on Grey Correlation Degree
日本福岛核事故达到事故等级最高的7级，发生了严重的放射性泄漏，对周围环境造成巨大影响。通过灰色关联分析方法，以福岛第一核电站西北60km处福岛县辐射剂量监测值为对照序列，对福岛县辐射剂量与放射性源，即福岛第一核电站受损机组的相关程度作相关分析。选择受损机组内压力值、水位值、厂区西门监测点辐射剂量、福岛第一核电站西北20km至30km处辐射剂量为相关参数，通过邓氏灰色相关度模型，计算得到各个参数与福岛县辐射剂量的相关度。发现各个因素对辐射剂量值的影响是不同的，其中堆内水位与压力对辐射剂量有着同等的较大影响。此分析可以为中国研究放射性扩散提供借鉴。
Fukushima nuclear accident is the most serious nuclear accident reached 7 level. The radiation diffusion of the accident has seriously affected the surrounding. According to the gray relational analysis, the radiation dose in Fukushima where is located in the northwest 60km away from the NPP is considered as the contrast sequence, studying on the degree of relevance between the radiation dose in Fukushima and the damaged nuclear power unit which is radioactive source. And the parameters of the damaged unit such as pressure and water level are considered as the contrast parameter. It is the same to the radiation dose in the west gate of the first nuclear power plant in Fukushima and the zone northwest 20km-30km away from the NPP. The effects of the factors are different and the water level is the most important. The analysis and result may contribute to the study of radiation diffusion in China.
