摘　　要：通道式辐射监测系统属于辐射在线检测范畴，为保证系统现场稳定运行的有效性和准确性，通过建立数学模型，找出构成稳定性偏差的要素和分量组成，利用试验考核并对测量稳定度进行分析和评定，分析后可知系统在测试现场环境下稳定运行输出值为5710．9cps，相对合成标准偏差为5．811％，k=3。按照分析结果判断，通道式辐射监测系统可以满足在线、长期、正常运行的要求。同时进行过程分析，找出引入偏差的因素，为进一步提升系统稳定性指明了方向。The G-type channel radiation monitoring system belongs to the field of online radiation monitoring. In ord6r to ensure the effectiveness and accuracy, we analyzed and evaluated the stability of the system through experiment, found out the stability of the deviation of the elements and components, and reached a conclusion by analysis about the system stable output value for 5710.9cps in the field test environment, synthesis of the relative standard deviation for 5.811%, k=3. According to the test and evaluation results, the G-type channel radiation monitoring system can meet the requirements of online, long-term and normal operation. And the same time, the process analysis is carried out to find out the factors which are introduced into the deviation, and to point out the direction for the further improvement of the system stability.
