为了对回旋加速器生产的放射性气体~(11)C直接进行定量监测,获得该同位素生产的总产额,我们设计了流气式电离室。其总的监测不确定度在7％之内,满足在线监测的要求。
In order to directly monitor the cyclotron-produced radioactive gas ~ (11) C and obtain the total output of this isotope production, we designed a flow-ionization chamber. The total monitoring uncertainty is within 7%, to meet the requirements of online monitoring.
