福岛核事故期间广西地区辐射环境应急监测

Emergency Monitoring of Environmental Radiation in Guangxi in the wake of Nuclear Accident at Fukushima in Japan

福岛核事故发生后,广西环保部门按照环境保护部核与辐射事故应急办公室的应急指令组织有关力量展开应急监测。监测内容包括γ辐射剂量率连续监测,以及空气、沉降灰、雨水、江河水、海水、蔬菜、土壤等环境介质中人工放射性核素水平监测。监测结果表明:气溶胶样品中监测到微量的131I、137Cs、134Cs,蔬菜和雨水样品中监测到微量的131I。这些核素的活度浓度极低,公众无需采取防护措施。

After nuclear accident at Fukushima in Japan, Guangxi Supervising Station for Radioactive Environment initiated the continuous monitoring of environmental radioactivity in Guangxi Zhuangzu Autonomous Region, involving air, rainwater, river water, seawater, soil, and vegetables. Trace amounts of 131 I, 137 Cs and 134 Cs were detected in aerosol sample and also trace 131I in vetetables and rainwater samples. The activities of these nuclides are very low so as not to take protection measures.
