Improved processing method reduces time required to generate a color radiograph. Prior to, or after exposure to penetrating radiation, the emulsion side of the film is flashed to a colored light which produces the hue changes in the processed radiograph. Agitation of the film during processing assures uniformity of results.
Youth space science model rocket projects in rocket motor design, static tests, propellant mixing, and rocket launch
Factors affecting continued technical information service subscription to the NASA regional dissemination center
Silver-cadmium secondary spacecraft cell acceptance tests
NASA Pilot Program in instructional monographs to provide up-to-date material from current research for engineering education
Sensitivities of various metal/halocarbon slurries to impact are given. Barium and lithium shavings show sensitivity with all of the halocarbons tested except methyl chloroform. Powdered aluminum, magnesium titanium, and beryllium show sensitivity with several halocarbons but generally require a higher level of initial energy.
