Abstract
A cathode ray tube has discrete x-ray absorbing means integrally associated with the face region thereof to beneficially attenuate the x-radiation emanating peripherally and forwardly therefrom. Attached to the tube face is a closed frame-like resilient gasket impregnated with x-ray absorbing material. Superposed thereon is a cover plate of x-ray absorbing glass. This is adhered to the tube face by a layer of substantially transparent adhesive confined within the gasket.
