Abstract
A bag (10) for transporting radioactive flood sources and the like is formed from a lightweight, multi-layer sheet material comprising a layer (42) of a high-Z, radiation shielding material sandwiched between inner and outer layers (46, 40) of protective material. The radiation shielding material is preferably formed from a lead or tungsten composite comprising a lead or tungsten powder dispersed in a polymer matrix, such as a lead/vinyl composite. The flexible bag is lightweight, allowing the flood shield to be transported easily by handles (26, 28), without the need for maneuvering the bag along the floor on wheels.
