Groningen radiocarbon dating laboratory
The findings from the most recent (completed in 2001) and extensive (more than 90 participating laboratories) radiocarbon intercomparison (FIRI) are reported here.
He did his doctorate in physics at the University of Heidelberg.Plans for a radiocarbon dating laboratory at the University of Lund were initiated by Tage Nilsson and Holger Arbman in 1962.Work was begun in 1964 and at the end of 1965 most of the dating equipment was installed.John developed the CSIR lab into one of four key high-precision dating laboratories in the world and provided an exemplary service to archaeology in southern Africa and around the world.Aside from his major role in establishing culture-historical frameworks, John developed techniques for dating unburnt bone, identified differences in the natural radiocarbon of the southern and northern hemispheres, and devoted much energy to understanding variations in the production of radiocarbon.International comparisons of laboratory performance are an essential component of the quality assurance process in radiocarbon dating.
If the user community is to have confidence in radiocarbon results, it needs to be assured that laboratories world wide are producing measurements that are reliable and in accordance with 'good practice'.
Topic of research: Development of a reliable approach to exact-year radiocarbon dating.
Exact-year radiocarbon dating has only recently become a viable prospect, spurred on by two methodological developments.
This Ph D project aims to unite both these innovations by developing a robust method for achieving exact-year radiocarbon dating.
The research will have practical and theoretical components.
The authors summarise the results of the fourth of these scientific audits.
