Basic discussion on electromagnetic radiation: Gamma radiation in relation to SPECT imaging

Abstract

This chapter describes the structure of the atom and explains the physical processes of radioactive decay, including electron capture, beta decay, and isomeric transition, which lead to the emission of gamma radiation. It describes different methods of producing radionuclides using cyclotrons, nuclear reactors, and radionuclide generators. A description of how gamma radiation interacts with matter leads to a discussion of the desirable properties of radionuclides suitable for SPECT studies.
