摘要
介绍了利用SAUNA惰性气体氙移动取样设备在我国某地区进行的惰性气体氙放射性本底调查的过程和结果,包括现场取样、样品传输和实验室分析等环节。在历时15天的本底调查中共采集分析了15个样品。研究结果表明,该地区大气中133Xe的活度浓度低于0.2 mBq/m3。
It mainly introduces the process and results of 133Xe background preliminary survey for a certain area of china by using a noble gas xenon mobile sampling system（SAUNA）.The survey process includes field sampling,sample transport and laboratory analysis of samples.15 samples were obtained and analyzed during two weeks survey period.The results show that the 133Xe activity concentration background of survey area is lower than 0.2 mBq/m3.
