ABSTRACT:
The exposure of a radiographic film to x-radiation transmitted through an intensifying screen during a period of exposure T is determined automatically in accordance with a method which achieves compensation for the effect of deviation from the reciprocity law by comparing a value representing the exposure attained by the screen-film pair with a reference value which is variable as a function of time in accordance with a predetermined law.
