The present disclosure provides a positioning assembly for a radiation irradiation system. The positioning assembly includes a shielding body made of polymer and radiation shielding material capable of shielding the radiation and a sealing bag for accommodating the shielding body, when the target to be irradiated is placed on the positioning assembly, the positioning assembly is recessed with a shape of the target at the position where the target is placed and forms a contour corresponding to the target to position the target to be irradiated.

A light-weight radiation protection panel comprising radiation protection layer and a flexible material. The radiation protection layer comprises a plurality of a shielding material distributed in repeated and adjacent units of geometrical shapes, the light-weight radiation protection panel being able to be embodied in a wearable garment providing flexibility.

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.

A shielding member for use in sterilizing drug container assemblies includes a housing. The housing includes a first shielding portion and a second shielding portion. The first shielding portion includes a first and second surfaces and a plurality of first bore portions extending between. The second shielding portion having a first and second surfaces and a plurality of second bore portions corresponding to and aligned with the plurality of first bore portions. The first and second bore portions cooperate to form a plurality of receptacles including a plurality of openings in the first surface of the first shielding portion of the housing. The receptacles are sized and configured to receive drug container assemblies, each comprising a container with a container contact region and a seal member disposed adjacent the container contact region to seal the contents of the container at a sealing interface, such that each drug container assembly is exposed out of the housing through one of the openings.

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.

[Object] To provide inorganic oxide flakes having excellent resistance to radiation damage. [Solving Means] Inorganic oxide flakes mainly composed of SiO.sub.2, Al.sub.2O.sub.3, CaO, and Fe.sub.2O.sub.3 are presented. The mass percentages of the components in terms of oxide in the flakes are set as follows: i) the sum of SiO.sub.2 and Al.sub.2O.sub.3 is from 40% by mass to 70% by mass; ii) the ratio Al.sub.2O.sub.3/(SiO.sub.2+Al.sub.2O.sub.3) (mass ratio) is in the range of 0.15 to 0.40; iii) the content of Fe.sub.2O.sub.3 is from 16% by mass to 25% by mass; and iv) the content of CaO is from 5% by mass to 30% by mass. The inorganic oxide flakes have enhanced resistance to radiation damage.
