The sensitivity variations in ionograplic emulsions Ilford G-5 and C-2, as a function of the temperature of exposure (20 to 110 deg ) were determined by total photometric and microphotometric measurements. The sensitivity of G-5 emulsions to alpha particles does not vary significantly with the exposure temperatures at 20 to 90 deg C if one develops the plates in a strong developer. The densities increase uniformly in a weakly reducing solution of pyrocatechine. Developed in Id-19, the C-2 emulsions become more sensitive to alpha panticles if the exposure temperature is increased for the ID-19. Pyrocstechine shows an increasing sensitivity with temperature. The microscope-photometric measurements done on the C-2 plates developed in ID-19 showed a progressive broadening of alpha -particle tracks with exposure temperature. (tr-auth)
