Abstract
For the sensitometric evaluation of screen-film systems, consideration of reciprocity law failure (RLF) is necessary because it affects the choice of exposure modulation method. The effect of RLF on determining characteristic curves of screen-film systems is experimentally evaluated by comparing time-scale and intensity-scale methods and by comparing different exposure times in the intensity-scale method. A specially designed x-ray sensitometer permits very precise exposures for both time-scale and intensity-scale sensitometry. Results are presented for Kodak Min-R and Dupont Lo-dose/2 screen-film systems.
