Device for protecting against ionising radiation and containment enclosure provided with such a device

A protection device for providing protection against ionizing radiation passing through an orifice defined by a wall bushing structure fitted with a glove, comprising:

• a sleeve;
• a structure for attenuating ionizing radiation passing through the orifice, which structure for attenuating ionizing radiation is configured to cover the orifice;
• fastener means 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 including an attenuation sleeve that is open at both ends, that is deformable under its own weight, that is configured to be fastened to the wall bushing structure by the fastener means at a first open end of the attenuation sleeve, and that is configured to be turned inside out to extend, in part, inside the sleeve of the glove.

A confinement enclosure comprising:

• a wall pierced by a first orifice;
• and
• a wall bushing structure engaged in the first orifice and defining a second orifice, the wall bushing structure being fitted with a glove comprising a sleeve and with a protection device providing protection against ionizing radiation passing through the second orifice,
• the protection device comprising an attenuation structure for attenuating ionizing radiation passing through the orifice, which attenuation structure is configured to cover the orifice, fastener means configured to ensure that the attenuation structure can be fastened releasably to the wall bushing structure, the attenuation structure including an attenuation sleeve that is open at both ends, that is deformable under its own weight, that is configured to be fastened to the wall bushing structure by the fastener means at a first open end of the attenuation sleeve, and that configured to be turned inside out to extend, in part, inside the sleeve of the glove.
