摘要
Abstract
Based on a high dose rate afterloading radiotherapy,the γ radiation level at inner entrance of the maze and the first transition in inner entrance of the maze as well as the outer entrance of the maze were calculated,and the influence of source' s location to the distribution of radiation level in the maze was analyzed through a monte-carlo code,whose reliability was tested by comparing with the results measured on-site.Results show that the radiation level in the maze strongly depends on the location of radioactive source in the treat room,and reach to a relatively lower level when the source locates at the east of treat room and close to the maze wall which can be recommended as an optimized location for source when executing the therapy.关键词
