摘要
本文介绍温、湿度变化对两种改进型被动式活性炭累积氡采样器吸附性能的影响。结果表明,温度(T)在15—35℃,相对湿度(R.H.)在33%—88%范围内,温、湿度变化对带扩散控制管采样器吸附氡量没有显著影响;对带烧结金属过滤器的采样器吸附氡量也只有较轻微的影响;而作为对照的常规采样器的影响则是显著的。
In this paper the performance of two kinds of samplers with diffusion control tubeor sintered metal filter is evaluated. The influence of variations of temperature(15—35℃)and humidity(33%—88% R.H.)on the quantity of ^(222)Rn adsorption by activated charcoal isefficiently eliminated.For comparision,the test shows that influence of variations of temper-ature and humidity on the conventional open-faced sampler is significant.
