Cosmic Radiations (Emulsions and Metals)

NSSDCA ID: 1961-026A-02

Mission Name: Discoverer 31
Principal Investigator:Mr. Robert C. Filz


Two groups of films coated with nuclear emulsions, arranged horizontally and vertically, were used to measure the intensity and direction of cosmic radiation and to distinguish among electrons, protons, and heavier charged particles. These emulsions were sensitive to neutrons, x-rays, and gamma rays. Nuclear track plates were included in the experiment package. The recovery capsule contained samples of various rare and common metals that were exposed to the space environment. The capsule failed to separate from the agena, and the recovery attempt failed.
