A shoulder transfer weight support generally having a hip or waist belt, a back support, and one or more shoulder extensions. The back support has an upper back plate attached to the shoulder extensions and a lower back plate attached to one or more hip belts. The lower back plate features a bracket shaped to receive an end of the attachment bar that joins it to the upper back plate. A spring-loaded plunger can be inserted into the attachment bar to allow for height adjustment of the device. A face shield at least partially made of a radiopaque material and can attach to the back support. One attachment option is a yoke mount with vertical sections at either end of the yoke mount. A second option involves a mount that attaches to the shoulder extension(s). The device can use a full face shield or a face shield with an open front.

Methods and systems for stabilizing spent fuel assemblies from sodium-cooled nuclear reactors using Zamak are described herein. It has been determined that there is a synergism between Zamak and sodium that allows Zamak to form thermally-conductive interface with the sodium-wetted surfaces of the fuel assemblies. In the method, one or more spent fuel assemblies are removed from the sodium coolant pool and placed in a protective sheath. The remaining volume of the sheath is then filled with liquid Zamak. To a certain extent Zamak will dissolve and alloy with sodium remaining on the fuel assemblies. Excess sodium that remains undissolved is displaced from the sheath by the Zamak fill. The Zamak is then cooled until solid and the sheath sealed. The resulting Zamak-stabilized spent fuel assembly is calculated to have sufficient internal thermal conductivity to allow it to be stored and transported without the need for liquid cooling.

A radiation shielded vault structure includes a rigid outer structure comprising a plurality of rigid structural components that are interconnected at elongated joints to define an interior space. The structural components include a layer of lower atomic number (Z) material such as aluminum alloy and one or more layers of higher atomic number (Z) material titanium and/or tantalum. The vault structure may include radiation shield members extending along the elongated joints to provide radiation shielding at the elongated joints. The shield members comprise a higher atomic number (Z) material such as titanium or tantalum. The rigid structural components may comprise plate members that are interconnected along side edges thereof. End plates may be attached to the plate members to close off the interior space.

The present invention relates to rigid structures and composite materials thereof for providing radiation attenuation/shielding. Some embodiments pertain to a radiation shielding apparatus including: a plurality of positionable radiation-shielding stacks of tiles. The stacks are subsequently and adjacently arranged in a contiguous configuration. A tile positioning mechanism allows movement of tiles within a stack between a stacked (retracted) position and an extended position. In the extended position, the tiles of each of the plurality of radiation shielding stacks at least partially overlap tiles of subsequent and adjacent tile stack at corresponding opposing side-margins thereof.

The present disclosure relates to a radiation shield device comprising a sheet of material comprising a plurality of flaps, wherein the sheet comprises a barrier to ionizing radiation. The present disclosure also relates to a method for manufacturing said radiation shield device.

A radiation shielding system for an x-ray digital detector array includes a first radiation shield having a plurality of shielding pads and a plurality of interstices between the plurality of shielding pads, the plurality of shielding pads having a greater thickness than the thickness of the plurality of interstices. The plurality of shielding pads is configured to be positioned over active components of the x-ray digital detector array and the interstices are configured to be positioned over passive components of the x-ray digital detector array.

A radiation protection device for an opening for inspection objects on a radiation tunnel is provided. The radiation protection device is formed from a plurality of radiation protection curtains arranged one behind the other at a distance in a transport direction, wherein a first radiation protection curtain includes a first shielding radiation protection curtain section covering only a first area of the opening and second shielding radiation protection curtain sections of at least one second radiation protection curtain arranged behind the first radiation protection curtain in the transport direction cover the area of the opening not covered by the first radiation protection curtain.

A shield structure configured to protect a head and/or neck of a patient during a radiologic procedure comprises a bottom wall, a side wall, and an opening. The bottom wall includes radiation attenuating material and is configured to be positioned between the head and/or neck of the patient and a radiation source so as to shield the patient from radiation directed toward the bottom of the patient. The bottom wall is of a general size to shield the head and/or neck of the patient. The side wall includes radiation attenuating material and is configured to extend upward from the bottom wall so as to shield the patient from radiation directed toward a side of the patient. The opening is configured to receive the head and/or neck of the patient.

Systems, devices, and methods are described for providing, among other things, an intra-oral x-ray imaging system configured to reduce patient exposure to x-rays, reduce amount of scatter, transmission, or re-radiation during imaging, or improve x-ray image quality. In an embodiment, an intra-oral x-ray imaging system includes an intra-oral x-ray sensor configured to communicate intra-oral x-ray sensor position information or intra-oral x-ray sensor orientation information to a remote x-ray source.
