Reduced integral solutions for gamma absorbed dose from Gaussian plume.

Exact two-dimensional and asymptotic one-dimensional integral solutions were obtained for the external dose rate value due to a Gaussian plume. The relative error of the asymptotic solution was found to be less than 5% for downwind distances of 1 to 300 mean free path lengths and for crosswind distances of 0 to 40 mean free path lengths. A good agreement was observed with the results of plume dose rate calculations published earlier.
