The Radiocarbon Dating Laboratory of Tehran University Nuclear Centre began operation in autumn 1970. Benzene synthesis and liquid scintillation counting was chosen as the best method for processing a large number of archaeologic specimens most of whose ages are less than twice the half-life of C14. Advantage of benzene synthesis; ease of chemical processing light transfer properties, lack of isotopie fractionation and radioactive contamination, removal of radon, and improbability of cross-contamination, have been discussed (Noakes et al., 1964; Noakes, Stipp, and Hood, 1964; Kowalski, 1965).
