CALCULATION OF THE SPECTRAL-ANGULAR DISTRIBUTION OF SCATTERED $gamma$- QUANTA FROM A MONODIRECTIONAL CESIUM-137 SOURCE IN IRON (in Russian)
The Monte Carlo method was used for calculating the spectral and angular distribution of the scattered energy of gamma quanta, emitted with an initial energy of 0.661 Mev by a Cs/sup 137/ point source placed in an infinite Fe medium. The 5420 measurements were carried out by determining the path of the quanta up to the first interaction, determining the type of the interaction, and calculating the energy of the scattered gamma quantum by the Compton effect; at the same time the direction of the flight path after scattering was also determined. The measurements were repeated until the quantum disappeared as the result of the photoeffect or because of transition to an energy level below 10 kev. Angular integration of the scattered radiation spectra showed that the energy of the quanta is limited within 0.13 to 0.26 Mev. The data obtained made it possible to calculate the buildup factor B/sub E/ of a flat, monodirectional source. (TTT)
