RADIATION SHIELDING

摘要

Various configurations of shielding materials within shielding layers, such as for use in shielding radiation from implanted radioactive carriers, are discussed herein.

主权项

1. A shielding apparatus comprising:
a collagen substrate; a plurality of shielding materials embedded in the collagen substrate, the shielding materials each comprising a high-z material, wherein the shielding materials are positioned within the collagen substrate to match positions of a corresponding plurality of radiation sources arranged according to a dosimetric plan, at least some of the radiation sources arranged with gaps between the at least some of the radiations sources and adjacent of the plurality of radiation sources; wherein when the apparatus is placed on the plurality of radiation sources,
each of the shielding materials provides substantial shielding of radiation emitted by a corresponding radiation source and reduced shielding of radiation from other of the plurality of radiation sources; andgaps between respective shielding materials provide less distortion of magnetic energy than the shielding materials.
