摘要： 用EXCEL计算双板源辐照装置照射场方法，包括坐标系的建立，单棒对空间某一点的照射率，多棒叠加合成空间某一点的照射率，某一时间的钴源活度。通过辐射剂量场分布的计算结果与实际测量值比较，基本反映了本辐照中心辐射剂量场的实际分布。

Abstract: It is discussed in this paper that methods of calculating dose field in a 60Co irradiation device with a pair of irradiation source frame by Microsoft excel. They are separately discussed that setting up a coordinate system in an irradiation field, calculating dose rate at a point in a Euler space by a single thread source, calculating dose rate at a point by all thread souces, and souce active at certain date. Applications at our irradiation center show that methods are correct.
