The γ-radiation fields which are in air 1, 300 and 500 m above the uniformly distributed γ-radiation source on a smooth ground surface were calculated by the Monte-Carlo method. The energy and angular distributions of γ-photon flux above the radiation source were obtained for 1.25 Mev and 0.67 Mev source energy (corresponding to γ-ray energies of Co~(60) and Cs~(137) respectively). Eor each sovrce energy, the scattered photon flux in each of 8 energy intervals between 0.04～1.5 Mev and 9 angle intervals between...

Furthermore, climatic effects made by effect-belt were analysed synthetically. The results are as follows:The index of confused and turbulent flow were changed by extension of effect-belt.
