The disclosure is directed to devices for use in radiation therapy. Various configurations of shielding materials within shielding layers, such as for use in shielding radiation from radioactive sources within implanted radioactive carriers, are discussed herein.

Collimators and other components for use in neutron scattering experiments or to provide neutron shielding in nuclear reactors or accelerator based neutron sources are produced by additive manufacturing from multiple different types of material, such as boron carbide (B.sub.4C), steel, isotopically enriched boron carbide (.sup.10B.sub.4C), and blends thereof.

The present invention relates to a lead free glossy finish hybrid radiation shielding composite panel comprising: a) 40-70% of industrial waste red mud and 30-60% of epoxy/polyester resin with or without glass fibre, wherein the composite panel has density in the range of 1.4-2.2 g/cc; water absorption in the range of 0.20-0.30%; tensile strength in the range of 12-120 MPa; tensile modulus in the range of 1.5-7.5 GPa; and half value layer in the range of 0.36-0.47 cm and 0.48-0.52 cm for X-ray beam energies of 60 and 100 kVp, respectively. The present invention also describes a low temperature process for manufacturing the composite panels. Moreover, the developed composite panel is a unique material and have multifunctional applications in wider spectrum as high energy electromagnetic radiation shielding doors, panels, partition panels and as roofing sheets.
