Sensitivity of x-ray film. II. Kodak No-Screen film in the 1–100-keV region

Abstract

The absolute sensitivity of Kodak No-Screen x-ray film was measured for 11 photon energies between 1 and 8 keV using filtered fluorescent radiation. The shapes of the density-vs-exposure curves were observed to be a function of the photon energy. This calibration was demonstrated to be consistent with two earlier calibrations of No-Screen response for photon energies between 5 and 100 keV and with a theoretical model of film sensitivity by Brown, Criss, and Birks.
