Abstract: In the nuclear science and technology disciplines of professional teaching,it is need to carry out the nuclear radiation detection,radiation dosimeter,radiation protection and other course experiments.There is a risk of radiation source management and radiation safety.This paper discusses the using of virtual simulation platform for the experiment,which based on the MC simulation technology.Through the virtual simulation on the PC,students can be familiar with the process of the experiments,improve the success rate and reduce the time with radiation source.At the same time,based on MC simulation technology,some difficult physical experiments can be modified,some lack of conditions experiments can be made up.The result is shown that the virtual simulation technology in nuclear science and technology disciplines practice is important and meaningful to the radiation experiment.
