A protection device for providing protection against ionizing radiation passing through an orifice defined by a wall bushing structure. The device includes a structure for attenuating ionizing radiation passing through the orifice, which structure can cover, or close off, the orifice, and includes a fastener configured to ensure that the structure for attenuating ionizing radiation can be fastened releasably to the wall bushing structure. The structure for attenuating ionizing radiation includes a sleeve that is open at both ends, that is deformable under its own weight, and that is configured to be fastened to the wall bushing structure by the fastener at a first open end of the sleeve. |
