摘要
Abstract
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).关键词
