The dates reported here represent a portion of thosedetermined in 1966, The Radiocarbon DatingLaboratory of the Instituto Venezolano deInvestigaciones Científicas carries out a synthesisof benzene for each sample and detects the activitywith a liquid scintillation spectrometer. Forroutine measurements, 3 cc synthesized benzene and 1cc commercial toluene, with PPO and dimethyl-POPOPscintillators, are used in a special small countingvial. The modern standard is 95% of the NBS oxalicacid, which gives a net modern count rate of 23.9cpm. The background is now 8.5 cpm.
