摘要 为满足监测环境大气中^(85)Kr活度浓度的需要,研制了常温下^(85)Kr取样浓集装置。该装置采用中空纤维膜法浓集环境空气中^(85)Kr,可有效地克服现有低温活性炭阱浓集吸附装置中低温控制部分安装和操作繁琐的缺陷,实现在常温下对^(85)Kr取样的浓集和测量,提高了环境大气中^(85)Kr的取样与监测水平。性能测试表明:该装置满足设计要求。 In order to monitor the 85 kr activity levels in the atmosphere, thes5 kr sampling concentration device at room temperature is developed. The device adopts the method of hollow fiber membrane to concentrate 85 kr in the ambient air. The device can effectively overcome the installation and operation cumbersome defects of the existing cryogenic trap concentration active carbon adsorption device in low temperature control part and implement the 85 kr concentration of sampling and measurement at room temperature, improve the sampling and monitoring level of 85kr at environmental atmosphere. The performance testing shows that the device meets the design requirements.
