LEAD SHEET FOR RADIATION PROTECTIVE BARRIER, RADIATION PROTECTION BARRIER, AND EXECUTION METHOD FOR RADIATION PROTECTIVE BARRIER

摘要

PROBLEM TO BE SOLVED: To provide a lead sheet for a radiation protective barrier reduced in generation of a fragment material, required to develop no smoothness, reduced in elongation, and easy to be executed, a radiation protective barrier using the lead sheet for the radiation protective barrier, and an execution method for the radiation protective barrier.;SOLUTION: This lead sheet for the radiation protective barrier concerned in the present invention comprises rectangular sheet-like lead rolled in a roll-like form having 320-480mm of width and 1-3mm of thickness, and creep strength of the lead is within 22-41kPa of range. The lead is preferably lead added with 0.02-0.08% of Ca and/or Sb in lead having 99.99% or more of purity.;COPYRIGHT: (C)2005,JPO&NCIPI
