A radiation attenuation corridor couples a radiation therapy room and a control room. The radiation attenuation corridor is made of a material that substantially absorbs ionizing radiation and substantially blocks the transmission of the ionizing radiation. Specific wall portions at the entrance of the corridor are covered with borated polyethylene (BPE). Specific wall portions diverge from an axis defined by the corridor by from about 10 degrees to about 45 degrees. The corridor thus leads out of the room and angles laterally across the wall of the therapy room, before angling again and opening to a safe room. The added angles in the radiation corridor increase the distance of radiation travel, and make the path more indirect, thereby increasing the contact of the radiation emissions with the radiation shielding and further attenuating the radiation.
Facility for installing or for system testing of floor or ceiling-mountable x-ray systems with radiation protection cabins with radiation-proof, especially lead-lined, walls and doors, with each radiation protection cabin (1) having a sliding door (7, 7') occupying at least a majority of the cabin wall, made up of several lead-shielded door elements (7a, 7b, 7c) which can slide telescopically over one another and are preferably hung from a ceiling mount at a slight distance from the floor to allow them to slide freely and separate the internal operating space (5) of the cabin (1) from the operating console (4) for the x-ray system arranged in front of it, with the door elements (7a, 7b, 7c) being equipped with lead-shielded side edges (9) overlapping in their closed position such that radiation cannot escape from the interior of the cabin through the gap between two adjacent door elements (7a, 7b, 7c), and with a door closing monitoring system being provided to which the operating system of the x-ray system is connected.
