摘　　要：本文介绍了碘连续监测仪的现场运行实验及其结果。结果表明该监测仪的性能稳定。仪器具有自动调整测量周期功能和快的响应时间,能十分灵敏地给出流出物中^(131)Ⅰ浓度随时间的变化规律。其测量结果与累积取样并经γ谱仪分析的方法比较。在30%内相符。该监测仪能满足核设施正常运行及一般事故监测要求。This report describes the test in the field and measuring results with a continuous iodine monitor.The measuring results show that properties of the monitor are stable,the monitor has not only a function of auto- matically adjusting measuring period and fast respose time hut also can very sensitively give out regulation of ^(131)I concentration varied with time.We have compared the results measured by continuous iodine monitor with the resultz analysed by accumulative sampling with gamma spectrometer.Both agree within ±30%.It can be used for measuring the release from the nuclear facilities in normal operation and general accident con- dition.
