The radiocarbon laboratory, operated by the Department of Physics and the University Museum at the University of Pennsylvania, is concentrating its analyses in four fields of archaeology: the Middle East, Middle America, South America, and the Arctic. It is the policy of the laboratory to publish radiocarbon dates only in groups from one specific field after checks and rechecks of related materials result in a certain measure of internal consistency (Ralph 1955: 149-51; Coon and Ralph 1955: 921-2).

The radiocarbon laboratory at the University of Pennsylvania is sponsored jointly by the University Museum and the Physics Department. In this laboratory our primary function is to date archaeologic samples from those four regions of the world in which the University Museum studies are concentrated, namely, the Near East, South America, Central America, and the Arctic. Dates for sites in the first two regions are included in this list, and a long series of temple lintels from Tikal, Guatamala is now being processed. Dates for the Arctic were obtained intermittently from 1953 through 1955 (with solid-carbon counting); others, more recently. The materials for many of the Arctic dates, however, were not reliable; that is, they were physically contaminated before processing in the laboratory. We hope that better samples can be found for future Arctic dating. Our Arctic dates which now furnish tentative age ranges for Punuk, Birnirk, Kachemak Bay III, Okvik, Old Bering Sea, Ipiutak, Norton, Dorset, Kachemak Bay I, Choris, Firth River (Early Mountain Phase), Sarqaq, and Denbigh Flint Complex Periods have been submitted to American Antiquity (Rainey and Ralph, in press) along with detailed discussions of possible contaminations.

In 1940 Professor Thurstan Shaw excavated a trench in the cave known as Bosumpra at Abetifi (6° 41′N:0° 44′W) on the borderline between the moist forest and the northern marginal forest (fig. 1). Bosumpra is one of the four main ‘abosom’ (lesser) gods of the Guan pantheon (Brokenshaw 1966, 156). The report (Shaw, 1944) showed that the cave was formerly inhabited by a people with a pottery-using microlithic culture and provided the first analytical description of the microlithic industries from the forest regions of West Africa. As the site was the first of its kind to be excavated, and the excavation was carried out before the advent of radiocarbon dating, there was no way of knowing what age this industry was, or how long the cave had been occupied, beyond placing it within the rubric of the so-called “Guinea Neolithic”.To attempt to clarify this problem a group of students from the Department of Archaeology at the University of Ghana and myself conducted the excavation of a small witness section (fig. 2) in the cave over New Year 1973/74 with the specific aim of collecting organic material for dating. We were fortunate in finding adequate amounts of charcoal at all levels. Two of these samples were submitted to Rikagaku Kenkyusho, Japan, for dating.

A radiocarbon dating laboratory was installed at the University of Wisconsin in 1963 as part of a program of climatic research in which meteorologists, archaeologists, chemists, botanists, limnologists, geologists, and soil scientists are cooperating.

The radiocarbon dating laboratory in the Institute of Marine Science at the University of Alaska was established in the fall of 1968 and became operational a year later. Most of the samples examined have been from Alaska and consist largely of wood and peat.

The University

Plans for a radiocarbon dating laboratory at the University of Lund were initiated by Tage Nilsson and Holger Arbman in 1962. Work was begun in 1964 and at the end of 1965 most of the dating equipment was installed. Dating began in 1966 after careful testing of counting electronics and counters.The dating system has two 1-L copper-walled proportional counters of Östlund-Engstrand construction (for details see Stockholm V. p. 204, Fig. 1) surrounded by 2.5 cm of selected lead, followed by a ring of 23 cosmic-ray Geiger counters (model HZ-100, Zentralwerkstatt Göttingen). On all sides are at least 20 cm of iron. Above and on both long sides of the counters are 10 cm of paraffin wax with about 12% boric acid between the iron layers.

The Impact

It is a commonplace of current archaeology that the publication of radiocarbon dates is revolutionizing our ideas of the past. Dr G. H. S. Bushnell, Curator of the Museum of Archaeology and Ethnology in the University of Cambridge, England, has already published in ANTIQUITY and elsewhere some of his views on the impact of radiocarbon dating on New World chronology. Here he studies the whole problem in detail. He adopts the useful convention of referring to a date already fully published in the Radiocarbon Supplement to the American Journal of Science simply by its laboratory designation and number {thus K-554 is reading no. 554 of the Copenhagen Laboratory), but in some cases, where the date is not fully published, he gives fuller information.
