钴源辐照装置剂量场的EXCEL计算法初探

Dose Field Calculation of a ^(60)Co irradiation Device by Microsoft Excel

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。

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.
