Abstract: A radiation shield comprises a wrappable sheet of radiation-shielding material such as lead-filled plastic sheet faced on one side with a vinyl facing sheet and on the other side with a sheet of heat-resistant material. Releasable contact-fasteners, preferably of the type sold under the trademark Velcro, are affixed to the wrappable sheet, as by being attached to the vinyl facing sheet, to provide first and second complementary locking portions of the fasteners. The radiation shield is dimensioned and configured to be wrapped around a radiation-emitting structure such as a conduit or pipe to encircle at least a segment of the structure; the Velcro.RTM.-type fasteners affixed to the sheet are so dimensioned and configured that with the shield wrapped in encircling engagement about the structure, the first and second complementary locking portions are brought into contact and secured to lock the radiation shield in place.
