Measurement of 14C Activity by Liquid Scintillation Counting

Measurement of 14C activity in various types of samples has been performed in the Zagreb Radiocarbon Laboratory since 1968 by proportional counting technique and since 2001 by liquid scintillation (LS) technique by using LSC Quantulus 1220. We either prepare benzene or absorb CO2 obtained from the sample in a scintillation cocktail. Various measurements protocols were developed for different type of vials. Examples of environmental 14C activities in atmospheric CO2 and in biological samples are presented.
