摘要
在一些设备室和实验室中,可能存在同一区域布置多个带源项设备的情况。为了对同一区域内多个设备中的源项同时进行监测,提出了一种多设备源项的区域监测方法。该方法通过蒙特卡罗程序,确定各设备材料成分、几何尺寸及探测系统相关的响应矩阵,利用数值模拟或实验测量得到某工况下各探测器的探测响应计数,利用反演算法求解各设备的源项,实现对同一区域内多个源项的监测。数值模拟实验表明,该方法是可行的,能够实现对于区域内重点关注源项设备的监测,可缓解探测器中干扰的问题。
In some laboratories and equipment rooms,there might be the cases where multiple equipments with source items are arranged in the same area.In this paper,a method is proposed to monitor the source terms of multiple equipments in the same area simultaneously.The method uses Monte Carlo code to determine the response matrix related to the content in each equipment,geometric size,and detection system.The detection response counts of each detector under a certain condition are obtained by numerical simulation or experimental measurement.The inversion algorithm is used to solve the source items of each equipment.And then,the monitoring of multiple source items in the same area is realized.The numerical simulation experiment shows that the method is feasible and could monitor the key source items of multiple equipments within the same area.The method could alleviate the problem of detection response counts fluctuation.
