To obtain statistically valid results from ionization measurements in photographic emulsions, it is necessary to establish the technique so that it gives quantitative results which are independent of deviations in the sensitivity of the emulsions and in methods of development. The problem consists of finding suitable parameters which represent the blackening state from point series as a function of the energy loss of the particles producing tracks. In a discussion of the problem, the grain density and specific energy loss, ionization parameters in emulsions, and model representation of the occurrence of point series are considered. An analysis of the results of experimental investigations leads to expressions describing the relationship between auxiliary parameters and to the determination of the grain density in the tracks.
