Abstract

Assuming that the Compton phenomenon is mainly responsible for the scattering in the block of metal, there was calculated the deposit of radiation at the bottom of the cylinder originating from its wall. The calculation was made for the primary spectrum 0 - 6 MeV given for Clinac accelerator. Klein - Nishina relations were taken as describing an elementary scattering event. The radiation intensity recorded on photographic material was compared to that evaluated as the incoherent summation of contributions. Supposing the caustics arising it was shown the possibility of the change of the intensity distribution.
