【摘要】 本文报道了一种用于核设施周围环境和工作场所气载放射性碘监测的 DQ—01型碘取样器的性能试验结果。试验测定了采样流量、相对湿度及温度等因素对该取样器捕集放射性碘的效率的影响。试验结果表明,在环境温度和相对湿度小于95%下,即使取样流速高达1061 cm/s,床深6 cm 的取样器对甲基碘的捕集效率也大于95%。更多还原

【Abstract】 In this paper the results are reported of the performance test of model DQ-01 iodine samplerused for monitoring air-borne iodine in workshops and areas surrounding nuclear facilities.The effectsof several factors.such as gas flow rate.relative humidity and temperature,on the efficiency of samplerwere tested.The test results indicated that at ambient temperature and relative humidity less than 95%,the capturc efficiency of sampler with charcoal bed of 6 cm depth for methyl iodide was larger than95% even if the sampling flow rate was higher than 1061 cm/s.更多还原
