Theγ‐ray skyshine due to radioactive point‐source was simulated with MCNP in this paper .Moreover ,the main factors which affect γ‐ray skyshine were studied ,and the conclusions provide references for corresponding radiation protection of nuclear pow‐er plant .The γ‐ray skyshine dose rate due to radioactive waste lifting at nuclear power plant was evaluated specifically ,and a rapid evaluation method of γ‐ray skyshine dose rate due to radioactive body‐source was founded by use of the results of radioactive point‐source .T he implementation of this method meets the engineering rapid response requirement effectively .
