ABSTRACT:
A radiation shielding structure including a radiation shielding panel which comprises a lead transparent plate, for example, a transparent lead acrylic resin plate, lead glass plate, etc., and a thin nonlead transparent plate, for example, a transparent acrylate resin plate, glass plate, etc., which is laminated on at least one side of the lead transparent plate. Thus, lead that is contained in the lead transparent plate shields radioactive rays, while the nonlead transparent plate, which is laminated on at least one side of the lead transparent plate, prevents oxidation of the lead in the lead transparent plate by air or chemicals, which oxidation would otherwise form an oxide film on the panel surface and make the panel opaque.
