Abstract : A brief survey is made of present knowledge of the composition and energy spectra of the primary cosmic radiation. The total energy carried by all forms of cosmic radiation that have appreciable penetrability into matter has been evaluated. This information, when combined with a knowledge of the rate at which the different components deposit energy in traversing matter, would permit calculations of the radiation dose that would result from exposure to the primary cosmic radiation. It is concluded that overall these radiation effects are rather small but it is emphasized that local damage can be of much greater significance. (Author)
