PHOTOGRAPHIC RESPONSE TO X-RAY-IRRADIATION .2. CORRELATED MODELS

In this paper models from the first paper are generalized so that they include the correlation of attenuation coefficients and coverages wit h emulsion depth. They avoid further assumptions and can provide physi cally meaningful parameters (as opposed to earlier studies); thus clos er agreement with experimental measurements is obtained. The difficult y in estimating correlated overlap functions is discussed. Error estim ates resulting from grain statistics are generalized and computed in a self-consistent manner. Contributions to granularity from densitomete r and grain statistics have been shown to be significant or dominant i n most emulsion types. The formulation derives reliable error estimate s. Correlated models are important for thick emulsions such as DEF-392 , whereas integral formalisms may be as useful for thin emulsions. In agreement with the first paper, reciprocity failure appears to be negl igible for UV or x-ray energies above 9 eV.
