摘　　要：随着核与辐射在人们日常生活中的应用越来越广泛,其所带来的危害也备受关注。剂量估算是辐射技术应用的重要一环,估算出人体所受的剂量对评价辐射造成的确定效应与随机效应起着重要作用。蒙特卡罗(MC)模拟与人体参考模型结合可对核事故、医疗照射和环境的辐射剂量进行估算,是一种快速且对硬件要求较少的剂量估算方法,目前正面临模型开发和计算耗时的瓶颈,笔者对此现状进行综述。With the increasing use of nuclear and radiation in people's daily life,the harm caused by radiation has also received much attention.Dose estimation is an important part of the application of radiation technology.Estimating the radiation dose received by the human body plays an important role in determining the deterministic and random effects of radiation.Monte Carlo simulation combined with the human reference model can estimate radiation doses of nuclear accidents,medical exposures and environmental radiation.It is a fast and low-hardware dose estimation method.Currently,it faces bottlenecks in model development and calculation.This artical reviews the research progress.
