14C Dating with the ICELS Liquid Scintillation Counting System Using Fixed-Energy Balance Counting Window Method

Abstract

This article presents an application of a fixed-energy balance counting window in radiocarbon dating of geological peat samples. We determine a fixed-energy balance counting window with an inexpensive liquid scintillation counting ICELS system. We show long-term modern biosphere standard records that show stability sufficient for dating samples up to approximately 30,000 14C yr BP. We then compare our results to ones obtained previously using a Quantulus 1220™.
