Radiation shielding struc tures of walls doors and window connections

摘要

The present invention relates to a radiation shielding structure for a wall, a door, and a window connecting portion, and includes a shielding wall 100, a shielding door 200 for accessing the X-ray imaging room, and a shielding window 300 installed between the X- Claims [1] A radiation shielding structure for a wall, a door and a window connecting portion, comprising: The end of the shielding wall 100 on the side of the shielding door 200 forms the stepped portion 105 and the end portion is covered with the softening plate 106 so that the surface of the softening plate 106 is coated with the color paint 107; The shielding door 200 has a structure in which a galvanic steel plate 201, a soft plate 202, a honeycomb filler 203, and a galvanic steel plate 201 'are sequentially laminated; The end of the shielding door 200 is brought into close contact with the stepped portion 105 of the shielding wall 100 so that the end of the shielding wall 100 and the end of the shielding door 200 are overlapped with each other; The center of the end of the shielding wall 100 on the side of the shielding window 300 forms a step 105 'and an end portion of the shielding wall 100 is covered with the plate 106' so that the surface of the plate 106 ' Is applied; An end portion of the shielding window 300 is brought into close contact with the stepped portion 105 'of the shielding wall 100 so that the end portion of the shielding wall 100 and the end portion of the shielding window 300 are overlapped with each other, , γ-ray, and neutron beam can be surely shielded, but the use and post-management cost of lead can be minimized, and it is possible to shorten the air by a simple construction and significantly reduce the disclosure ratio. to be.
