The following list covers measurements of bomb-producedC14 in series of cereals and grassescollected on the northern hemisphere from 1956through 1966. Samples were measured in order todetermine the yearly addition of bomb producedC14 at a single locality, and to detectpossible geographic variations in the distributionand uptake of bomb-generated C14 interrestrial plant material during years with greatlyvarying additions of bomb C14.Measurements are given in the ∆ scale (Lamont VIII),i.e. per mil deviations from 0.95 times the activityof the NBS oxalic-acid standard (the naturalC14 level).
