After a severe accident in nuclear reactor like Fukushima power plant for the on-site scenario, some staffs could not evacuate with personal vehicles especially in China. Faced the simulation requirement of evacuating by foot in microscopic field, here we will introduce the lattice-gas model of pedestrians evacuation with two dimensional grid dynamic analysis, combined with Gaussian puff model to calculate the scale of personal radiation risk for their trajectories discretely and respectively. The purpose of this paper is to give informatively route selection designed for the plan of nuclear emergency preparedness work in responding large amount leakage of radionuclide, and cope with the problems from evaluation of nuclear accident emergency management and regulation. Our results also illustrate comparison data and targeted countermeasure in the corresponding suggestion, and giving advice for individual and crowd. A simplified application is presenting in demonstrations in a nuclear power plant under constructed at south China.
