摘　　要：研制了一种可在十分恶劣的环境条件下工作的塑料闪烁探测器,该探测器具有双层减振结构,其内部各主要部件与壳体之间采用了非刚性连接,具有良好的减振性能及环境适应能力。在随机振动、冲击、高低温、高低气压以及湿热等环境试验考核中,所有的探测器均能正常工作,大多数探测器输出幅度的稳定度小于20%。A kind of plastic scintillation detector is developed to be used in very terrible environments. Each detector has two layers of damping structure and its main parts are not connected rigidly. These detectors can damp random vibration and adapt themselves to variation environments very well Many environment experiments have been carried out such as random vibration, impact, high （low） temperature, high （low） air pressure, etc. All detectors work well and the output of most detectors changes less than 20 %. This kind of detector can be used to measure neutron fluence in some special environments.
