ENVIRONMENTAL EFFECTS OF PHOTOSENSITIVE MATERIALS.
Abstract
The report covers the second phase effort to develop an experimental device for use in a probe or orbiting type space vehicle to collect qualitative and quantitative data on the nature and effects of space environmental radiation on gelatin-silver-halide emulsions. The flight instrumentation package to be developed will include a film supply, image processor, image data readout device, and data processing circuitry compatible with standard research vehicle telemetry. An experimental laboratory unit was developed incorporating a film processor, photo densitometer, and radiation counter which were designed for operation in a space vehicle. The operation of the unit is controlled by an electro-mechanical programmer and is capable of continuous automatic processing of a roll of film. Supporting investigations of rapid processing of selected aerial films and the results of an investigation of web processing techniques are also reported. (Author)
