Electron radiograph receptor

A three layer receptor sheet for positioning at an electrode of an imaging chamber to produce an electronradiogram, consisting essentially of an optically transparent dielectric plastic core layer of substantially constant resistivity arranged in contiguous relation between an optically transparent dielectric plastic image carrier layer and an antistatic electrical conducting layer, said image carrier layer having a substantially constant resistivity of at least 10.sup.14 ohms per square unit of area for receiving on its exposed face an electrostatic image of charges generated externally of the sheet and retaining said charge image while in contact with said core layer and exposed to light, said antistatic electrical conducting layer having a substantially constant resistivity in the range of about 10.sup.1 to about 10.sup.12 ohms per square unit of area.
