A radiation shielding material that is lighter and has lower installation restrictions than conventional methods, and that exhibits excellent shielding efficiency against radiation in the high energy region. The radiation shielding material comprises a complex containing a fibrous nanocarbon material, a primary radiation shielding particle, and a binder, wherein the fibrous nanocarbon material and the primary radiation shielding particle are dispersed in the binder.

A radiation system includes a support, a capsule rotatably coupled to the support, a radiation source movably coupled to the capsule, wherein the radiation source is configured to provide a treatment radiation beam, and is capable of being turned on or off in response to a control signal, and a collimator located next to the radiation source, wherein the capsule defines a space for accommodating a portion of a patient, and includes a shielding material for attenuating radiation resulted from an operation of the radiation source, and wherein the shielding material is configured to limit a radiation exposure level to 5 mR/hr or less within 5 meters from an isocenter.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) or other materials are processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the walls and optionally the ceiling include discrete units. Such vaults are re-configurable.

Methods for setting up, maintaining and operating a radiopharmaceutical infusion system, that includes a radioisotope generator, are facilitated by a computer of the system. The computer may include pre-programmed instructions and a computer interface, for interaction with a user of the system, for example, in order to track contained volumes of eluant and/or eluate, and/or to track time from completion of an elution performed by the system, and/or to calculate one or more system and/or injection parameters for quality control, and/or to perform purges of the system, and/or to facilitate diagnostic imaging.

An exam room shielding (10) for electromagnetically shielding a magnetic resonance imaging system (2) includes: a ceiling, a floor, side walls (11) interconnecting the ceiling and the floor, and a tubular shielding device (12), which is arranged to surround an examination tube (3) of the magnetic resonance imaging system (2). Both longitudinal ends (13) of the tubular shielding device (12) are circumferentially connected to openings (14)of the side walls (11) which form the outline of an U-shaped room (15) with the longitudinal ends (13) of the tubular shielding device (12) interconnecting the lateral flanks (16) of the U-shaped room (15). A magnetic resonance imaging system (2) includes an exam room (1), with the above exam room shielding (10). An additional treatment or diagnosis device (7) can be located at an outer circumference of the tubular shielding device (12). This separates the space inside the exam room into a compartment free of RF noise, i.e. the space surrounded by the exam room shielding, for MR scanning, and a compartment outside the shielding, in which an operator can move for operating the MR imaging system and/or preparing a person for a MR scan.

A radioactive waste container, for storing and transporting a radioactive waste, includes a container body, a cover and a water drain unit. The cover is fastened to the container body. The water drain unit is provided at the container body without protruding to an outside of the container body and configured to selectively drain water in the container body.

A system for manufacturing radionuclide generators including an enclosure defining a radioactive environment, at least one autoclave sterilizer within the enclosure, and at least two loading and unloading elevators. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. Each autoclave sterilizer includes a plurality of sterilization stations arranged vertically and at least two autoclave rails. One loading and unloading elevator is configured to load a cart into the autoclave sterilizer and one loading and unloading elevator is configured to unload the cart from the autoclave sterilizer. Each loading and unloading elevator includes at least two cart rails configured to support the cart and a plurality of loading elevator rails coupled to the cart rails. The loading elevator rails are configured to adjust the height of the cart rails.
