Abstract: A magnetic shielding material includes a material comprising manganese bismuth (MnBi) and tungsten (W), where a ratio of MnBi:W is in a range of 50:50 to about 70:30. A radiation shielding product includes a part including manganese bismuth (MnBi) and tungsten (W), and a plurality of layers having a defined thickness in a z-direction, wherein each layer extends along an x-y plane perpendicular to the z-direction. At least some of the plurality of layers form a functional gradient in the z-direction and/or along the x-y plane, and the functional gradient is defined by a first layer comprising a ratio of MnBi:W being less than 100:0 and an nth layer above the first layer comprising a ratio of MnBi:W greater than 0:100.

Abstract: A radiation attenuation shield, method, and system are disclosed. The shield includes a polymer, a radiation attenuating material, and a magnetic material. The radiation attenuating material and the magnetic material may be dispersed within the polymer to form an attenuation layer. Further, a magnetic material layer may be positioned adjacent to the attenuation layer or encase the attenuation layer. The radiation attenuation shield may be made by combining the components to create a mixture and then inserting the mixture in a mold until a solidified shape is formed. Moreover, the radiation attenuation shield of the present invention may be mechanically secured to a structure to contain radiation. Further, the shield may be secured to a structure by using the magnetic properties of the shield.
