A device for protection of a body from radiation includes at least one flexible garment. Each section of the flexible garment is configured to shield a region of a surface of the body. Each section complementarily attenuates self-shielding by internal structure between the region and an interior region of the body such that radiation at the interior region is attenuated to a predefined attenuation level.

The present invention relates to a method of preparing a lead-free radiation shielding sheet with excellent shielding performance not only in a high energy (100 kVp) band but also in a low energy (50 to 80 kVp) band and improved durability of the sheet. bands without containing lead. The radiation shielding sheet of the present invention uses antimony (Sb), which has a high shielding rate even in the low energy band instead of lowering the content of tungsten having a relatively lower shielding rate in the low energy band than in the high energy band, thereby increasing the shielding performance in both high energy (100 kVp) and low energy bands. Further, the radiation shielding sheet of the present invention may increase not only durability, but also elasticity, tearing strength, and tensile strength by mixing additives such as zinc oxide with the rubber.

Waste capsules for disposal of radioactive materials, including weapons grade plutonium, are made entirely from rock, such as, but not limited to, granite; wherein a cap of such a waste capsule is seamlessly rock welded to a lower body portion of the given waste capsule, to form the given waste capsule, with the radioactive materials inside of a cavity of that waste capsule. The weld region is homogenous with both the cap and the lower body portion. A cooling system may be used during or after rock welding. The sealed and rock welded waste capsule, with the internal radioactive materials, is then loaded into a wellbore system that extends into a deep geological rock repository, thousands of feet below the Earth's surface, such that the waste capsule comes to rest in a wellbore located within the deep geological rock repository. The waste capsule may include insulating material in the cavity.

An on-body injector system includes a drug container assembly including a container, a seal member, and a sealing interface between the seal member and the container. The container includes an opening and the seal member at least partially covers the opening in the container. A fluid pathway assembly is coupled to the drug container assembly and includes a needle that is movable between a storage position, in which a point of the needle is spaced from the seal member, and a delivery position, in which the point of the needle is disposed at least partially through the seal member. A radiation generator is configured to emit rays of radiation to sterilize and/or disinfect the sealing interface. A barrier is disposed adjacent to the sealing interface and has an opening. At least a portion of the drug container assembly is positioned adjacent to the opening in the barrier.

A radiation protection material (10) is arranged between at least two layers (21, 22) of at least one plastic-containing element in order to produce a radiation protection element. At least part of the gas present between the at least two layers (21, 22) is removed. The at least two layers (21, 22) are connected with each other.
