Abstract : The work is part of a study of detection of nuclear explosions by satellite instruments. To examine the effect of scattering of X rays by the atmosphere before detection at a satellite, Monte Carlo calculations have been made for point monoenergetic sources of 10 Kev, 30 Kev and 100 Kev at altitudes from 30 km to 150 km. Results are given for the ratio of scattered to vacuum energy deposition as a function of satellite observation angle, and for the energy spectra observed at fixed angles of observation. (Author)
