摘　　要：日本福岛核电站事故后,广东省环境辐射监测中心从3月13日起,利用γ能谱法对广州、深圳等地区采集的各类样品进行放射性监测。3月15日首先在飞机擦拭样中监测到131Ⅰ、134Cs、137Cs、136Cs、132Ⅰ、132Te等人工放射性核素,随后又在气溶胶、碘盒、沉降灰、雨水样品中监测到了人工放射性物质。初步探讨了广州地区空气中人工放射性核素与局地风向的关系,广州地区与深圳地区空气中131Ⅰ的比较。137Cs/134Cs活度比与日本方面测得的统计值(1.00±0.13)相近。The γ-ray spectrometry had been applied in the radiation monitoring in Guangzhou （GZ） and Shenzhen （SZ） by the Guangdong Environmental Radiation Monitoring Center （GERC） since March 13, shortly after the hydrogen explosion of Fukushima Dai-ichi Nuclear Station. Artificial radionuclides of 131I, 134C8, 137C8, 136Cs, 132I, and 132Te were detected initially from the aircraft wipe samples on March 15,then in samples of aerosols, iodine cartridge, deposition and rainwater. In this paper, the author preliminarily discussed the correlationship of airborne artificial radionuclide concentration in GZ district with local wind direction,and also compared the airborne 131I concentrations in GZ and SZ. The ratio of 137Cs/134 Cs was found close to the monitoring data statistics of Tokyo Electric Power Company（1.00 ±0. 13）.
