近年来，时有发生的海洋核事故引起了人们对海洋放射性监测的重视。为了充分了解海洋放射性的特征，应用海水就地γ能谱仪进行了海水本底、点源及体源实验，同时进行了相应的MC模拟。模拟谱与实测谱的对比发现两者的主要特征基本相符，γ能谱变化规律一致，体源探测效率和探测下限的模拟结果与实际值基本一致。结果表明，海水就地γ能谱的MC模拟是可行的，模拟不仅可作为实验的重要补充，并能为海水就地γ能谱测量提供可靠的相关参数。

In recent years , the occasionally occurred marine nuclear accidents caused the people 's attention to marine radioactivity monitoring .This paper attempts to study the characteristics of marine radioactivity and γ-ray spectra .The seawater in situ γ-ray spectrometer was applied to some experiments , such as:the seawater background , point source and volume source experiment .At the same time , the paper carried on the corre-sponding Monte Carlo ( MC) simulations.The simulated spectra compared with the measured spectra showed that they are basically consistent .The simulation results of the volume source detection efficiency and the limit of detection are accord with actual values .The results show that MC simulation can be used as an important supplement of the experiment , and provide reliable parameters for seawater in situ γ-ray spectrometer .
