In general, radiation shielding systems that shield radiation from multiple directions are described. In one embodiment, a method of shielding radiation is provided, including supporting a shielding device on an object proximate a radiation source, positioning a first shielding portion in a vertical position relative to the object, positioning a second shielding portion to extend away from the first portion, the second shielding portion attached to the first portion, and shielding radiation from the radiation source by the first shielding portion and the second shielding portion such that the first and second shielding portions provide a radiation shielding zone for a healthcare practitioner.

A medical imaging system for detecting ionizing radiation. The system includes one or more pixilated imagers positioned to acquire patient image data and one or more position sensors positioned to acquire patient position data. Once the patient image data and patient position data are acquired, one or more processors operably connected to each of the one or more pixilated imagers and one or more position sensors calculate a three-dimensional mass distribution based on patient image data and patient position data.

Various embodiments relate to devices for transporting high-assay low-enriched uranium (HALEU). A device may include at least one section, wherein each section of the at least one section includes a number of storage tubes. Each storage tube, which is configured to receive and hold a container, extends from adjacent a first end of the section toward second, opposite end of the section. Each section further includes a number of flux traps, wherein each storage tube of the number of storage tubes is at least partially surrounded by a flux trap of the number of flux traps Associated systems are also disclosed.

A compression member for insertion into a pig for transporting a container of biohazardous materials includes a flange maintained in spaced relation with an annulus by pillars; and spaced apart pivotable grip components supported by the annulus and extending downwards from the annulus between respective ones of the pillars towards, but not into contact with, the flange, the pivotable grip components resiliently compressible inwardly against the container when the container is received within the compression member. In use, the compression member receives at least a closure portion of the container and, in turn, is itself received within a complementary annulus of the pig. When being received within the complementary annulus of the pig, the pivotable grip components are urged inwards towards the container thereby to grip the container and provide a spacer for between this portion of the container and the pig.

The present technology is directed to barium-133 (“Ba-133”) based standards that simulate expected energy emissions of iodine-131 (“I-131”), and thus can be used to calibrate radioactivity measuring instruments (e.g., dose calibrators) used to measure the radioactivity of I-131 drug products. The Ba-133 standards can be manufactured in geometries typical of those used to administer I-131 drug products, including, for example, as a capsule, a syringe, a vial, etc.
