The dependences of the sensitivity and gamma of radiographic materials on the ratio of developing agents metol and hydroquinone, and methylphenidone and hydroquinone in processing formulation were investigated. The obtained data allow us to identify the areas of synergetic relations of developing agents. Studies were carried out in the conditions of both separate development and fixation, and simultaneous development and fixation. Control guides were two types of radiographic materials – RT-K (fine grained low sensitive) and RT-1 (more coarse-grained and highly sensitive) films. Exposure and photographic processing were carried out in standard conditions.
