Abstract
A radiation shield (2) for a flexible tube such as a source guide tube (4) of a radiography projector system, said shield comprising a flexible sleeve (6) comprising an axial assembly of axially overlapping tubular units (10) of elastomeric material containing particles of radiation attenuating material. In a preferred embodiment, the tubular units each comprise a female section and a male section disposed at opposite ends of the unit, said male section being adapted to be a push fit into the female section of a like unit. The sleeve is preferably protected by a sheath (8) e.g. of a braided metal wire. Also described is a flexible source guide tube assembly for use with a radiography source projector system, said assembly comprising a flexible source guide tube within a radiation shield in the form of a flexible sleeve for the tube, said sleeve comprising elastomeric material containing particles of radiation attenuation material.
