Abstract

The C (super 14) Dating Laboratory of the University of Texas has been working on the development of 2 systems of counting: gas counting with methane, and liquid scintillation counting with benzene. Lack of adequate instrumentation has retarded the work on gas counting, but the liquid scintillation work, supported in part by the Dept. of Chemistry, finally led to the successful development of a system in which the benzene counting solvent was synthesized from acetylene by pyrolysis. Three geologic check samples are described from North Dakota, Alaska, and Illinois. Fifteen archaeologic samples are described from Oklahoma and Texas.
