摘　　要：本文分绍了一个用于辐射防护和医疗目的的蒙特卡罗程序。它能计算出受到光子照射时人体20种器官(组织)的吸收剂量和人体有效剂量当量。程序中使用了一种特殊的方法以加快计算结果的收敛。本文所介绍的方法也可用于其他复杂几何系统的剂量计算。A Monte Carlo code applied to radiation protection and medical radiology is presented. It simulates the irradiation caused by photons and can give the effective dose equivalent (He)and absorbed dose equivalents of 20 organs (tissues) in a reference man. A special method which divides all photon histories into several kinds and traces each kind separately was adopted to improve the precision of the calculated results.The code can be also used to other calculations of doses in systems with complex geometry.
