摘　　要：水环境的污染和破坏已成为当今世界主要的环境问题之一,随着水环境受放射性污染事故的增多,对水环境进行放射性监测很有意义。基于传感器+通用采集卡+计算机的硬件,在.NET开发平台进行虚拟仪器软件设计,研制了水样品自动采集系统和γ能谱测量系统,并将二者进行集成,实现了水样品的自动采集与测量。通过对雨水短寿命核素放射性水平监测实验的结果分析表明,该系统能够有效实现江、河、湖泊、海洋以及降雨等水体进行放射性监测,且具有自动化程度高、性能稳定、可扩展性好的优点。The pollution and destruction of water environment has become one of the main environmental problems in the world today.With the increase of radioactive pollution accidents to water,i t is very meaningful to carry out radioactivity monitoring of water environment.In this paper,a water sample automatic quantitative collection system and a gamma-ray spectrum measurement system are developed based on sensor,common DAQ and computer with virtual instrument software designed on.NET development platform.The two systems have been integrated to realize automatic water sampling and measuring.Through The results of monitoring the radioactivity level of rainwater,this system can realize radioactivity monitoring of rivers,lakes,seas and rainfall,and results show that the system is highly automated,stable and extensible.
