Section: abstract

A radiation shield, and a radiation shield assembly. The shield assembly is designed to allow use of conveniently fabricated radiation shield portions to provide a single completed radiation shield. The shield portions are mechanically fastened together, preferably with deck screws. A completed radiation shield assembly is coated with a flexible elastomeric epoxy coating to protect the radiation shielding material, preferably lead, from becoming dislodged. Preferably, the radiation shield is provided in a sequence of layers, with each layer having one or more radiation shield portions. In an alternate embodiment a lightweight, portable radiation shield is provided which has an inner layer with at least one sheet of solid radiation shielding material, an outer stainless steel casing, and a sealant located between at least portions of the at least one sheet of solid radiation shielding material and the outer stainless steel casing. Flanges on the stainless steel casing are fastened together, preferably by riveting to seal the casing. A stainless steel U-shaped cap is provided at the top of the shield for extra protection during use. The sealant and the stainless steel casing, including the cap, cooperate to effectively seal the solid radiation shielding material against leakage outward through the outer stainless steel casing.
