Discussion Reporting of ¹⁴C Data

TLDR

In 14 C laboratories, raw count rates are converted to ages or geochemical parameters, but the steps between counting and reporting create complications. The authors aim to identify problems in 14 C data reporting and recommend procedures to avoid ambiguities. They analyze reporting pathways and propose standardized procedures to reduce ambiguities. They find that small variations in reporting pathways lead to inconsistent results, hindering inter‑laboratory comparisons.

Abstract

Count rates, representing the rate of 14 C decay, are the basic data obtained in a 14 C laboratory. The conversion of this information into an age or geochemical parameters appears a simple matter at first. However, the path between counting and suitable 14 C data reporting (table 1) causes headaches to many. Minor deflections in pathway, depending on personal interpretations, are possible and give end results that are not always useful for inter-laboratory comparisons. This discussion is an attempt to identify some of these problems and to recommend certain procedures by which reporting ambiguities can be avoided.
