NettetIntroduction A comparatively large variety of interactions can occur when -rays penetrate matter. Often it is possible to isolate these effects and to con sider them separately. … Nettet6. jul. 2024 · We covered the interaction of gamma-rays with matter from a descriptive viewpoint in the previous chapter and we saw that the Compton and Photoelectric Effects were the major mechanisms. We will consider the subject again here but this time from an analytical perspective. This will allow us to develop a more general understanding of …
NettetThe previous chapters of this book have dealt with the production mechanisms for γ-rays in the nuclear transition region and the expected intensity of γ-rays (particularly of discrete energy) from various astrophysical sources. In order to discuss the experimental side of this field, it is necessary to review the fundamentals of the ...

NettetGamma rays ionize matter primarily via indirect ionization. Although a large number of possible interactions are known, there are three key interaction mechanisms with … NettetGamma rays are often considered the most dangerous type of radiation to living matter. Unlike alpha and beta particles, which are charged particles, gamma rays are instead …
NettetPair production can occur when the gamma-ray energy is greater than 1.022 MeV and is a significant process at energies above 2.5 MeV. The process produces a positron and electron pair that slows down through scattering interactions in the matter. When the positron comes to rest it annihilates with an electron producing a pair of 511 keV …
NettetRadiation Cross section and Compton scattering. A useful concept in describing the absorption of radiation in matter is called cross section; it is a measure of the probability that photons interact with matter by a particular process.
