• Radiocarbon Dating of Intercomparison Samples at the Zagreb Radiocarbon Laboratory

      Horvatinčić, Nada; Srdoč, Dušan; Obelić, Bogomil; Krajcar Bronić, Ines (Department of Geosciences, The University of Arizona, 1990-01-01)
      The Radiocarbon and Tritium Laboratory of the Rudjer Bošković Institute, Zagreb, participated in the International Collaborative Study (ICS) in all three stages. All measurements were made by proportional counting of methane. We present here a statistical analysis of our results. A comparison with the mean or median values of reported ICS values showed that our results are generally slightly younger.
    • Statistical Quality Control Graphs in Radiocarbon Dating

      Switsur, Roy (Department of Geosciences, The University of Arizona, 1990-01-01)
      I describe here the establishment and use of statistical control graphs based on the analysis of variance for monitoring the stability of operation of radiocarbon dating counting systems.
