Abstract

In order to estimate the various effects of radon progeny on the gamma-ray dose rate observed at the ground surface, a computational program was newly developed for the calculation of gamma-ray dose rate at the ground surface due to radon progeny in the atmosphere around a complicated topography. The results obtained in this study are as follows. (1) Not only vertical distribution but also horizontal distribution of the atmospheric radon progeny must be considered for the accurate estimation of gamma-ray dose rate at the ground surface. (2) Important information can be obtained about the quantitative topographic effects on the gamma-ray dose rate at the ground surface that were not usually considered. Using the developed program, gamma-ray dose rate at the ground surface due to the arbitrary vertical and horizontal distribution of radon progeny in the atmosphere can be calculated taking topographic effects into account.
