Abstract : A set of empirical equations is produced to calculate the fractional arrival rate of radioactivity of the ground where the radioactivity is the result of a nuclear surface burst. A total of 20 such equations are given for four log-normal particle size distributions and five nuclear yields from 1KT to 15MT. The fractional arrival rate of radioactivity on the ground, g(t), data for the 20 cases were generated by a fast running fallout smearing code. The results were fit with a sixth degree Laurent series for each of five particular yields. For each size distribution the Laurent series coefficients for the five yields were then fit with a polynomial function of yield to enable computation of g(t) data for any arbitrary yield between 1KT and 15MT. Calculation of g(t) data with these empirical equations may be accomplished on a hand held calculator and produce results which are accurate to within at least 4 percent of the fallout smearing computer code data.
