A high-pass radiation shield for using during radiological examinations is provided. The shield comprises: a first sublayer having a first radiation attenuation material of atomic number from 21 to 30; and a second sublayer having a second radiation attenuation material of atomic number 56 or greater. The weight of the second radiation attenuation material is not greater than the weight of the first radiation attenuation material. The shield is configured for placement on a patient's body over the entire or a portion of the field of view (FOV) for protection of the organs, especially radiosensitive organs against radiation dangers emitted by an X-ray tube without degrading image quality.

The present invention provides a radiation shielding material, particularly for shielding of particle radiation, comprising a fibre material and a radiation damping filler, wherein the amount of the radiation damping filler is 40 to 95 wt. % based on the dry weight of the radiation shielding material. The present invention further provides a radiation shielding structure, particularly for shielding of particle radiation, comprising a bottom layer and a top layer, wherein a hollow structure is sandwiched between the bottom layer and the top layer, wherein the hollow structure is filled with a radiation damping filler.

Disclosed is a composite material, comprising a polymer, a plurality of metal nanoparticles, and a surface-modifying agent (e.g., nanocellulose). Also disclosed is a method for shielding a subject from electromagnetic radiation, comprising placing one or more composite materials between the subject and a source of electromagnetic radiation, thereby reducing a dose of electromagnetic radiation received by the subject.

Certain embodiments are described that are directed to lead free compositions including radiation absorption metals in combination with a polymeric material. In some aspects, a composition includes at least one heavy metal, other than lead, known to have shielding capability against ionizing radiation and at least one polymer, polymer blend or co-polymer. Sheets and articles including the compositions are also described.

Conformal coatings provide environmental protection for sensitive military electronics. Preliminary MCNP™ modeling of metal oxide impregnated acrylic conformal coatings indicates an effective shield for gammas below 10 keV and a reduction in neutron displacement damage to Si-based electronics across the Watt spectrum. This work provides data which can allow an optimal overall shielding worth per total weight to eventually be evaluated.

A protective assembly comprises a first region formulated and configured to provide protection from alpha, beta, and electromagnetic radiation and comprising a composite of particles and polymer; a second region formulated and configured to provide protection from ballistic impact and comprising a composite of fibers and polymer; and a third region formulated and configured to provide protection from thermal radiation and comprising a composite of particles, fiber, and polymer. The protective assembly may be provided on an aerospace structure. The protective assembly may be formed on the aerospace structure body using a co-curing process.

Radiation-shielding composite materials and their methods of manufacture. Such methods may include adding a metal hydride to a hardenable matrix precursor, adding a reinforcing material to the hardenable matrix precursor, and hardening the matrix precursor to form a composite material that incorporates the reinforcing material and the metal hydride in a solid matrix. The resulting radiation-shielding composite materials are configured to attenuate incident radiation, and may be used in the construction of panels, laminate structures, buildings, and aerospace vehicles, among others.

A radiation scatter anesthesia protection system designed to attach to a procedure table to limit exposure to radiation for both medical staff and a patient. The radiation scatter anesthesia protection system includes a headboard adapted to be disposed adjacent the patient's head. Headboard shielding including a first sheet of shielding extending downward from the procedure table, a plurality of additional sheets of shielding removably mounted to the headboard, and a molded head shield extending from the headboard. A frame disposed adjacent the procedure table. First and second outer side curtain shields suspended from the frame. First and second central curtain shields disposed between the first and second outer side curtain shields and suspended from the frame.

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.

Polymeric compositions for use in nuclear applications that exhibit long-lasting protection from degradation in the presence of oxygen (e.g., air) and high energy radiation, even when utilized in high temperature applications are described. The polymeric compositions include a particulate additive that incorporates a zinc-based solid-state antioxidant. The antioxidant can be a binary or ternary zinc-based material that can include one or more additional metals and optionally can include oxygen.
