摘要
文章提出了在强^(60)Co源辐照装置里,为了获得最佳的辐射场分布,在双栅板源板上,设计出用单一比度源棒的一种理想可行的源棒排列方案。提出了衡量源棒排列设计的标准,即辐射场的不均匀度和累积照射量率的不均匀度。并绘出了等照射量率的分布曲线。
A desirable arrangement of single specific activity source bars of double platefor optimum field distribution of strong ^(60)Co irradiator is proposed. Two parame-ters, non-uniformity of radiation field and non-uniformity of total accumulationexposure rate, are suggested as the design criteria. The distribution curves ofconstant exposure rate are given in the paper.
