Effect of Iron Inclusions in Asbestos on Electrical Characteristics of Insulating Material - Detection of Iron Particles by X Radiography

Abstract

Fine metallic particles present in fabric tapes used for electrical insulation may be detected by x-radiography using soft radiation and fine grained film, enlargements from which will show the metallic particles to better advantage than a microscope. Tests were made with this method of a number of commercial asbestos tapes and impregnated tapes used for cable wrapping.
