摘要
利用标准面源来模拟核材料库的γ辐射场,从实验和理论两方面研究了移走某一放射源后四个不同监测位置γ辐射强度的变化规律。结果表明,移走监控对象中某一放射源后,不同检测位置γ辐射强度的变化规律是唯一的,并与理论计算符合得很好。据此完全可以确定核材料的变化情况。
The technology of positioning nuclear components in a simulating nuclear material storage was investigated by the change of γ radiation field when some of components was moved out. Both theoretical calculation and experimental results indicated that the regulation of change of radiation field in different location was unique when a location of components was changed, by which the shift of the components could be determined.
