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 lognormal 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.
