摘要：
The significant factors which affect low-level counting of tritium by liquid scintillation have been investigated. In a typical operating mode of the system having a background of 8·5 counts/min, one count/min above background corresponds to 380 pCi/l of water (120 T.R.). The developed system combines convenience of automatic sample counting, room temperature operation, high efficiency, high capacity, and simplicity for effective application in measuring tritium levels in environmental samples. © 1969.
