A gamma radiography system includes a gamma source holder, a shaft handle attached to the source holder, a source container that surrounds the source holder, a source container cover attached to the source container to receive and slidingly support the shaft handle, a shielded housing that detachably receives the source container, and an extension connected to the shielded housing, such that an opening of the extension covers a beam aperture of the shielded housing. The shaft handle is configured to move the gamma source holder between a non-deployed position, in which the gamma source holder is surrounded by the source container, to a deployed position, in which the gamma source holder extends from the source container into the shielded housing.

A smart knee brace including a knee brace, multiple thigh bands, multiple shin bands, and multiple brace straps removably attached to one another and multiple motion actuators and sensors. Each motion actuator is connected to one brace strap and each sensor is connected to one motion actuator to measure an orientation of corresponding brace strap and generate a motion signal. A computing device receives the motion signals from the sensors; measures a current range of motion of the thigh, the shin, and the knee, and, based on the received motion signals, and generates drive signals based on the measured current range of motion. A native smart knee brace computer application on a smart phone of the user is operatively connected to the computing device and a cloud application server provide higher level analysis of the motions of the smart knee brace.

Neutron radiation can be attenuated by a material comprising acrylonitrile butadiene styrene (ABS) filament infused with gadolinium, boron, gold, and/or cadmium. The metal-infused filaments are 3D-printed to form a sleeve or cover for gamma and/or alpha radiation detectors to shield, absorb and allow detection of neutrons that are converted to gamma and or alpha radiation. The materials can also allow discrimination between neutron and gamma and/or alpha radiation in a mixed radiation field. Boron-infused filaments also provide neutron shielding and can be used in the manufacture of water equivalent phantoms.

An Actinium-225 generator is provided. The generator includes a neutron source; a neutron target arranged to receive neutrons emitted from the neutron source, wherein the neutron target comprises nickel; and a proton target arranged to receive protons emitted from the neutron target, wherein the proton target comprises radium-226. Methods for producing Actinium-225 are also provided.
