Rudjer Bošković Institute radiocarbon measurements VI
The following radiocarbon date list contains dates of samples measured since our previous list (R, 1979, v 21, p 131-137). As before, age calculations are based on the Libby half-life 5570 ± 30 yr and reported in years before 1950. The modern standard is 0.95 of the activity of NBS oxalic acid. Sample pretreatment, combustion, and counting technique are essentially the same as described in R, 1971, v 13, p 135-140, supplemented by new techniques for groundwater processing (R, 1979, v 21, p 131-137) and for soil sample treatment (R, 1977, v 19, p 465-475). Statistical processing of data has been computerized (0belic and Planinh, 1977). Sample descriptions were prepared with collectors and submitters. The errors quoted correspond to 1cr variation of sample net counting rate and do not include the uncertainty in 14C half-life. Calculations of age or percent of modern of speleothems and groundwaters are based on the initial activity equal to 0.85 of the NBS oxalic acid activity multiplied by 0.95. ACKNOWLEDGMENTS
