通道式车辆放射性监测系统的性能测试研究

Performance test and study of channel vehicle radioactivity monitoring system

通道式放射性监测系统作为出入口辐射监测最主要的手段,现已广泛应用于各监管场所的出入口,其性能参数的准确性、可靠性和稳定性直接关系着监测结果的准确可靠,关乎着国家和公众的安全。依托于所建立的通道式放射性监测系统校准装置,对国内市场上的20套通道式车辆放射性监测系统进行了全面的辐射性能测试研究。测试结果表明,不同型号的设备性能参数差异较大,并不能完全满足现有国家标准的要求。定期开展这类设备的性能测试研究,有利于尽快发现设备在使用过程中存在的问题,保证设备的监测能力。

Channel radioactivity monitoring system is the main means for entrance and exit radiation monitoring,it has been widely used in the entrance and exit of each supervision place.The accuracy,stability and reliability of its performance parameters are directly related to the monitoring results,which affect the national and public safety.The lab build up a calibration device for channel radiation monitoring system,which can meet the international and domestic requirements for its radiation performance testing.Twenty channel vehicle radioactivity monitoring systems’performance are tested comprehensively,they all being used in different places in China.According to the test results,the performance parameters of each monitoring system be tested vary greatly,which can not fully meet the requirements of exiting national standards.Performance testing of such equipments should be carried out regularly,which can help to find the problem as quickly as possible and ensure the monitoring capability of these equipments.
