Abstract
In a radiation shield in which a bag having flexibility is filled with a shielding liquid, a side of the bag is integrally equipped with reinforcement members which have a higher strength than the material of the bag and are longitudinally disposed and spaced horizontally. The bag filled with the shielding liquid is restrained from being deformed (swollen in its lower portion) by the reinforcement members having a higher strength than the material of the bag, so that the radiation shield is maintained in a predetermined thickness and exhibits predetermined performance.
