采用蒙特卡罗方法和MATLAB（Matrix Laboratory）程序对由576根钻源构成的辐照装置中剂量场均匀性进行优化设计。首先将程序计算结果与实验测量进行比较，接着对程序设置3200个计算点计算了辐照装置的剂量场分布；剂量场均匀性计算中，不断地改变钴源棒位置并不断计算空间平面剂量场。计算结果发现，程序计算值与实验测量值较为一致，经调整后装置的空间剂量均匀度显著提高，使得辐照装置的能量使用率大大提高。

This work is dedicated to design the dose field uniformity of irradiation facility installed 576 cobalt sources sticks by use of Monte Carlo method and MATLAB language. By comparing calculations with measurements the further calculation of dose distribution in the irradiation facility was performed by setting 3200 tally points of ir- radiation doses. In order to obtain the optimum data employed in our study, numerous position adjustments of the co- balt source sticks were made to calculate the dose distribution of the irradiation facility. And it had been found that there was a good agreement ...
