METHOD AND APPARATUS FOR RECORDING PATTERNS OF PENETRATING RADIATION

摘要

A method and apparatus suited for forming radiographs wherein distribution patterns of penetrating radiation representing radiographic information to be recorded are recorded in terms of electrostatic charge patterns on successive chargereceiving areas distributed along a carrier, by bringing such areas successively into a chamber in which each such area is exposed to an ionizable fluid while this is exposed in an electric field to a pattern of penetrating radiation thus producing in such fluid positive and negative charge carries and forming with the positive or negative charge carriers a corresponding electrostatic charge pattern on such area, the latter being brought by subsequent movement of the carrier to a position outside such chamber where such electrostatic charge pattern is transferable or developable to form a transferable visible record.
