註釋

The report presents and discusses the results of measurements with balloon-borne nuclear emulsion packs at supersonic transport altitude. The experimental design was such that the track population in the emulsion reflected directly the flux of low energy protons in the tissue equivalent material surrounding the emulsion on all sides. The radiation packs accompanied a main payload consisting of neutron spectrometer equipment. Packs were flown on a number of flights, each of them sampling a different altitude. No solar activity was recorded during the entire flight time; therefore, the data are representative of galactic radiation at solar maximum for a quiet sun. (Author).
