ABSTRACT:
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 charge-receiving 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 carriers 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.
