Study on Plastic Scintillation Detector Used in Very Terrible Environments

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. (authors)
