Abstract

Measurement of (14)C 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 counting (LSC) technique by using LSC Quantulus 1220. We either prepare benzene or absorb CO(2) obtained from the sample in a scintillation cocktail. Various measurement protocols were developed for different types of vials. Examples of environmental (14)C activities in atmospheric CO(2) and in biological samples are presented.
