【摘要】 介绍了利用热释光测量技术对自１９９４年投入商业运行的广东大亚湾核电站周围５０ｋｍ范围的环境γ辐射进行了常规监测。４年来的监测结果表明，核电站周围５０ｋｍ范围内的总体环境γ辐射水平没有发现明显的改变。但在靠近核电站１ｋｍ范围内的监测点上，１９９５年监测到有来自核电站排放的气载放射性流出物的影响。更多还原

【Abstract】 The paper presents the environmental γ radiation routine monitoring by TLD in Guangdong DaYa Bay Nuclear Power Station and its peripheral 50 km area, which has been put into commercial operation since 1994. The year′s monitoring result indicates that there is no obvious change of the total environmental γ radiation in Da Ya Bay Nuclear Power Station and its peripheral 50km area. But the influence of gas release γ radiation was monitored in 1995 at the monitoring points in the area of 0～1km from the nuclear power station.更多还原
