Comments
Comments Causes single and double strand DNA breaks with yields of 2.4 × 10-10 and 2.6 × 10-11 events/gy/DA [PUB_0485]. Proton radiation flux calculated from:
  • Total radiation at Clarkdale, AZ: 10-20 μrad/hr [PUB_0495]
  • Composition of radiation at Albuquerque, NM: mesons (63%), neutrons (21%), electrons (15%), protons (0%), alpha particles (0%) [PUB_0567]
  • Simplification that all proton radiation has energy 1 MeV. Kaye and Laby measured the energy distribution of protons at the earth's surface [PUB_0490].
