A liquid scintillation coincidence counter for radiocarbon

Measurements are made of the radiocarbon counting performance of a liquid scintillation coincidence counter used in conjunction with an anticoincidence shield counter. When operated at room temperature, the system has a radiocarbon counting efficiency of 59% at a background of 16 counts/min. The act...

Zusammenfassung:Measurements are made of the radiocarbon counting performance of a liquid scintillation coincidence counter used in conjunction with an anticoincidence shield counter. When operated at room temperature, the system has a radiocarbon counting efficiency of 59% at a background of 16 counts/min. The activity of ethanol made from contemporary wood is determined to 13.1 plus or minus 0.6 disintegrations per minute per gram carbon. (auth)
