Research and optimization of metal system device for conventional radioactive 14C dating
摘要
Abstract
Radioisotope 14C dating techniques are widely used in quaternary geology,archaeology,oceanography and paleoclimate.The conventional 14C dating method can record the number of 14C atoms by β decay low background liquid scintillation counter of a certain amount of samples in certain time inteval.As the equipment is simple and convenient,the accuracy of the test can meet the requirement of dating without being limited by the sample weight.The preparation system for 14C dating liquid scintillation method is mainly completed in the vacuum glass system,which is prone to breakage and fracture.Therefore a special welding master is needed in each laboratory to maintain and repair the vacuum glass system,which restricts the development of 14C dating techniques.This paper discusses the upgrading and transformation of the conventional 14C sample preparation system,and has developed a conventional 14C dating metal preparation system with metal material with the advantages of no glass welding,no oil pollution,easy installation and flexible disassembly.This system has solved the problems encountered in the development of conventional 14C dating,and can help promoting the application of regular 14C dating techniques.关键词
