摘要:
A Monte Carlo calculation was made of the energy dissipation by gamma radiation in a medium with the scattering properties of water which consists of two semi‐infinite regions, one of which is much denser than the other. The calculations are for a 1.28‐Mev point‐isotropic source at or near the boundary plane separating the two regions. The results are presented in terms of boundary correction factors which express the change of energy dissipation compared to that prevailing at the same location in a medium of uniform density. The analysis of the results leads to the conclusion that the boundary effect is rather insensitive to the atomic number of the medium, and is mainly a function of the density change. The Monte Carlo results are in good agreement with an experiment of Soole on the propagation of radiation in the air above the ground, and an experiment by Titus on the dose distribution in iron.
