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.
