Real time recording of X ray pictures without use of silver Halide films

Recording materials for deformation X-ray pictures were developed. In electroradiographic systems charge images are created which form deformation pictures on thermoplastic, elastic, or viscous layers. For continuous tones the deformation pictures have to be grated. On adjusted recording materials, charges of .0000000001 A/sq cm corresponding to 50 microns R X-ray exposures, were sporadically found. In ionization chambers, charges of .000000003 A/sq cm were shown with exposures to one mR.
