A method for simulating the effect of radiation at a certain point inside of vehicle originating the infinite surface contaminated uniformly with the radioactive material, has been studied. On the circumference of radius of about the length of a vehicle, a pole is set on which radioactive sources are distributed depending upon the distribution function calculated in this paper. The dose-rates of radiation at the same point are measured in the both cases: one is inside the vehicle and the other without vehicle and the ratio between both cases was calculated, which indicates the shielding-coefficient. An experimental example has also been made using a special vehicle. The shielding-coefficint of this vehicle was about 6%.
