Claim:
A radiation shield sheet, comprising: a raw utilizing sheet having a net structure defining a plurality of trapping meshes therethrough, wherein said raw utilizing sheet comprises a plurality of fibers and a plurality of matrixes reinforced together to define a fiber reinforced structure that forms said trapping meshes between said fibers and said matrixes respectively; and a shielding layer, which comprises a predetermined amount of radiation inadmissible material capable of attenuating an intensity of a predetermined amount of radiation, being fully and evenly coated on at least an exposure surface of said raw utilizing sheet, wherein a portion of said radiation inadmissible material is extended and captured into said trapping meshes to form a plurality of holding roots of the shielding layer so as to support and reinforce a layer of said radiation inadmissible material to be bonded on said raw utilizing sheet to form said shielding layer, wherein said radiation inadmissible material is lead which is capable of attenuating a predetermined amount of electromagnetic radiation impinging thereon; wherein said radiation shield sheet is produced by a method which comprises the steps of: (a) providing a piece of said raw utilizing sheet; (b) providing a predetermined amount of said radiation inadmissible materials at a predetermined form of existence, wherein said step (b) comprises a step of providing a pair of wires which are made of said predetermined radiation inadmissible materials, wherein two respective melting ends of said two wires are arranged to position very close to each other at a predetermined arcing distance; (c) raising the temperature of said radiation inadmissible materials to an extent of melting said radiation inadmissible materials so as to form a predetermined amount of coating residues; and (d) applying said coating residues towards said exposure surface of said raw utilizing sheet so as to coat said exposure surface with said coating residues for forming said shielding layer.
