Moon and space radiation

  1. Jan 11, 2013 #1
    ello,
    there is a knowledge that above earth's magnetosphere cosmic radiation is extremely high and unsafe for human life.
    the lowest point of earth's magnetosphere is 70.000 km,
    the range between earth and moon equals ~380.000 km,
    we know that moon doesn't have own magnetic field.
    So my question is -was astronauts damaged by cosmic radiation during appollo missions.
    if not-why?
    ty

    Radiation increases with height even on the surface of earth, rises significantly once you reach the Van Allen belt and drops again afterwards.
    For long journeys (to Mars, for example, or for a permanent base on Moon), this is a significant issue. For a few days, the radiation level is acceptable.
