摘要
介绍了一种新型的多点辐射检测系统的实现。阐述了该系统采用G-M管作为辐射探测器,以Time-to-Count技术作为测量方法,基于CAN总线网络完成多点辐射强度检测的软硬件实现技术要点。利用蒙特卡罗方法对Time-to-Count测量方法进行了计算机模拟,证明了Time-to-Count测量方法的可行性。实验结果显示,对于单个测量点的γ射线总量测量,J33型G-M计数管的线性测量范围可以达到20μR/h~30 000μR/h。
The implementation of an up-to-date multi-channel radiation detecting system based on CAN bus is presented. The software and hardware technical points are also introduced in details, such as using G-M tube as detector, Time-to-Count measure method, Controller Area Network(CAN) bus technique. The feasibility of Time-to-Count measure method is testified by using computer program according to Monte Carlo Simulation. The results show that the linearity measure range of J33 G-M tube can be 20 μR/h-30 000μR/h by Time-to-Count measure method.
