Abstract
The following list covers measurements of bomb-produced C14 in series of cereals and grasses collected on the northern hemisphere from 1956 through 1966. Samples were measured in order to determine the yearly addition of bomb produced C14 at a single locality, and to detect possible geographic variations in the distribution and uptake of bomb-generated C14 in terrestrial plant material during years with greatly varying additions of bomb C14. Measurements are given in the ∆ scale (Lamont VIII), i.e. per mil deviations from 0.95 times the activity of the NBS oxalic-acid standard (the natural C14 level).Keywords
