摘要
本文从提高单板源静态辐照的剂量均匀性和源利用率的观点出发,通过对辐射场剂量率分布数据和常用堆码方式的分析,提出了象限对角位移法和复合象限位移法等堆码工艺,从而改善了辐照剂量不均匀度,并提高了源的利用率。
The improvement of dose uniformity and the utilization efficiency of static irradiation with single plate source was carried out.The pile-up technology with substance displacing on an opposite angle in quadrant and multi-quadrant was suggested on the basis of dose distribution analysis and the ordinary pile-up method.
