COMPOSITE PLATE HAVING TRANSPARENCY SUPERIOR IN SHIELDING EFFECT FOR GAMMA RAY AND NEUTRON BEAM

摘要

PROBLEM TO BE SOLVED: To provide a composite resin radiation shield plate superior in shield effect for gamma ray and neutron beam, hardly generating bend or crack due to temperature difference, superior in anti-scratch capability, hardly causing color change and having transparency.;SOLUTION: The composite plate has a transparent lead-inclusive layer in the center layer and a transparent resin plate layer having neutron beam shield capability and a thickness of 10 mm or more. The transparent lead- inclusive layer and the transparent resin plate layer are polymerization-contacted with a bonding layer at storage elasticity of 1×10⁹ to 4×10⁹ Pa at 0°C and 1×10⁵ to 1×10⁸ Pa at 100°C.;COPYRIGHT: (C)2003,JPO
