钴源后装机源强度实验测量与蒙特卡罗模拟计算的比较研究
A comparative study on the actual measurement and Monte Carlo simulation about radiation intensity of cobalt source of afterloader device
摘要
Abstract
Objective: To carry out dosimetry study for the intensity of primal air kerma of the cobalt source of medical afterloader device. Methods: The experimental measurement of well-type ionization chamber and Monte Carlo simulation method were adopted to compare the dosimetry of primal air kerma between GZP3 of domestic afterloader device of cobalt source and Co0.a86 of Germany. Results: The deviation of intensity of primal air kerma between the experimental measurement and Monte Carlo simulation was within 3%, and the Monte Carlo models of the two types of cobalt source were verified. Conclusion: The primal intensity of intensity factor of air kerma per unit source activity based on Monte Carlo simulation can be applied in the test of quality control of cobalt source of afterloder device. The two type of Monte Carlo models of cobalt source which established in this study can be used to carry out correlatively clinical research of dosimetry.关键词
