Cosmic Radiation (Emulsions)

NSSDCA ID: 1961-016A-01

Mission Name: Discoverer 26
Principal Investigator:Mr. Robert C. Filz


Two groups of files 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 also included in the experiment package. A recovery capsule contained samples of silicon, iron, bismuth, yttrium, magnesium, nickel, lead, and uranium that were exposed to the space environment for 50.5 hr. The capsule successfully reentered the atmosphere after 32 passes, and the aerial recovery was accomplished.
