Abstract
Kodak Direct Exposure film (DEF) has replaced Kodak No-Screen film for use in x-ray diffraction analysis and in autoradiography. DEF is a double-emulsion film which has been found to have improved radiographic characteristics over No-Screen. A set of H-D curves has been generated for DEF at five photon energies: 0.930, 1.49, 1.74, 4.51/4.93, and 6.93 keV. The KMSF x-ray calibration facility was utilized to study the absolute sensitivity of this film over its full dynamic range. Physical examination of the film was followed by theoretical modeling, which adequately reproduced the measured curves.Keywords
