Radiological Protection and Medical Dosimetry for the Skylab Crew (SKYRAD)
Principal Investigator
Research Area:
Radiation biology
Species Studied
Scientific Name: Homo sapiens Species: Human

Skylab crewmembers needed protection from both expected and unexpected radiological events. Expected radiation events had components that were known with relative certainty whereas the unexpected events were completely indeterminate. The expected radiation sources were the trapped protons and electrons of the Van Allen Belts, galactic cosmic rays, and emissions from onboard radiation sources. Unexpected exposures might originate from energetic solar particle events, high altitude nuclear tests, and potential problems with the onboard sources already mentioned. The radiation plan outlined in this description was geared toward rapid identification of and reaction to any enhanced radiation situation.
