摘　　要：本文报道了一种适用于通道式车辆放射性监测系统的检测与校准方法,依据IAEA技术指导报告,从探测阈值、平均活度响应、活度响应非线性、有效探测区域、测量重复性等五个方面来检测通道式车辆放射性监测系统的综合性能,并探讨了动态测试的方法。结果表明上述检测与校准方法是合理可行的,对于有效防止监测系统失准、失灵从而造成放射性物质扩散具有现实意义。In this paper, a testing and calibration method for channel vehicle radiation monitoring system was presented through experiments on the basisi of the requirements of IAEA technical guidance. The comprehensive performance for channel vehicle radiation monitoring system was studied in aspects of detection threshold, average value of activity response, nonlinearity of activity response, effective detection area and repeatability, and simultaneously, a method for dynamic testing was discussed. The result indicates that the testing and calibration method are feasible, and that there are practical significance for effective preventing the spread of radioactive materials due to monitor system＇s inaccuracy and malfunction.
