Abstract: Ferrite powder is flame sprayed onto a glass or ceramic substrate to form a continuous coating, in which the powder is fused together and to the substrate to form a radiation shield. When the substrate is the glass envelope of a television receiver high voltage rectifier tube, such a shield in the correct location will absorb most of the X-rays that otherwise would be emitted by the tube.
