PROBLEM TO BE SOLVED: To provide an X-ray orγ-ray shielding equipment in which the space and material required for a shielding passage part can be significantly reduced. SOLUTION: In an X-ray orγ-ray shielding equipment in which an X-ray orγ-ray generating source 1 is enclosed by a shielding wall 2 having an opening part, a bent partitioning plate 4 is set in the opening part of the shielding wall 2 or a passage 3 leading to the opening part which uses the shielding wall as the outer wall (hereinafter referred to as shielding passage). The bent partitioning plate 4 is preferably set in such a manner that the outlet can not be directly seen from the shielding wall opening part or the inlet of the passage leading to it, and can be formed of a screen-like plate or spiral plate.
