[en] The relationship between scattered beams in radiation field, different tube-voltages, and thickness of steel plates was studied by experiments. The results show that radio parent ratio increases with increasing tube-voltage and decreases with the increasing thickness of steel plates. As scattering angle rises, the scattering ratio decreases slowly, and the lowest ratio is at 180 degree
