【摘要】 日本福岛核电站受地震影响发生事故后,中国辐射防护研究院随即启动了应急监测,监测内容包括γ辐射剂量率,以及气溶胶、空气碘、沉降灰、降水、地表水、生物和土壤等环境介质的放射性水平。监测结果表明:γ辐射剂量率没有发生明显变化;气溶胶、空气碘、沉降灰、降水、地表水和生物样品中均测出了131I,部分样品中测出了137Cs和134Cs;土壤样品中131I低于探测限。更多还原

【Abstract】 After the accident of Japan Fukushima Daiichi Nuclear power triggered by a magnitude 9.0 earthquake,CIRP quickly stared the emergency monitoring program of environmental radiation,including the measurements of the following media: γ dose rate,aerosol,air radioiodine,radioactive fallout,precipitation,surface water,organism and soil,etc.Monitoring results demonstrate that there is no obvious change about γ dose rate,the content of 131I in soil is below the detection limit,however,it reveals the presence of 131I in aerosol,air radioiodine,fallout,precipitation,surface water and organism.Contents of 137Cs and 134Cs were detected partly in the environmental samples.更多还原
