| Abstract: | Some data of radiocarbon dating for geological specimens with acetylene gas counting and liquid scintillation counting are given in this paper. The method of sample pretreatment and acetylene preparation as well as the experimental procedures and conditions in benzene synthesis are introduced here. In the counting of liquid scintillation, the decreasing effects of the lead screen on the background resulted from the soft component of cosmic radiation in the detector is considered. The form of sample container and volatility of benzene are also presented here. Finally, the results of radiocarbon dating are listed. |
