The Propagation of Gamma Quanta in Matter

The Propagation of Gamma Quanta in Matter deals with various problems of the propagation and absorption of gamma quanta in matter, including the occurrence of multiple scattering of radiation. A general account of theoretical methods of solving problems of multiple scattering of quanta is presented, with emphasis on the results of solving such problems.
This book consists of three chapters and begins with a discussion on the interaction of gamma radiation with matter; multiple scattering of gamma quanta; and the distribution function and quantities connected with it. The next chapter focuses on the theory of multiple scattering of gamma quanta and covers subjects such as the transport equation and its analytical solution; method of moments; method of random sampling; and method of successive collisions. The last chapter examines the propagation of radiation for various geometrical configurations of the sources and absorbing media, paying particular attention to a point source in a homogeneous medium and on the boundary of two media; unidirectional radiation in a homogeneous medium; reflexion of gamma radiation from the surface of a scattering medium; a plane isotropic source; and a thick radiating layer of an absorbing medium.
This monograph will appeal to students as well as physicists and engineers engaged in shield design problems.
