This book was released on 1968 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prospect of large-scale commercial passenger transportation at SST altitudes in the lower stratosphere calls for an accurate assessment of the galactic radiation exposure. Highest radiation levels prevail at high latitudes (polar region) and solar minimum and reach about 1 millirem/hour at 65,000 feet. The accumulated dose of 0.6 rem/year which an SST crew member spending 600 hours/year at altitude would receive exceeds the Maximum Permissible Dose (MPD) for 'Members of the Public' and would classify crew members as 'Radiation Workers' in terms of official recommendations. The assumption of 50 SST each exposing 200 passengers to 1000 hours/year at SST altitude would lead to a population dose about equal to the contribution from industrial radiation workers, with both exposures ranking well below the two largest man-made additions to the natural background, medical use of x-rays and fallout. The heavy flux is attenuated to 3 per cent or less at 65,000 feet, depending on the nuclear species; yet, only 0.1 per cent of this residual flux accounts for maximum ionization hits. That means the microbeam hazard of heavy nuclei is insignificant at SST altitudes. (Author).

This book was released on 1969 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
