1973 Radiocarbon: An International Journal of Cosmogenic Isotope Research  
This list presents results obtained during 1971-1972 and is a continuation of research evaluating natural C14levels for which data have been published previously (Baxteret al., 1969; Baxter and Walton, 1970; Farmeret al., 1972). The results of these studies are presented as δC14and Δ values based on age-corrected activities, although this correction is very small. Errors quoted are lσcounting uncertainties only. Pretreatment procedures are outlined in the text and analytical methods are
