The Origin of Neutron Radiation
摘要
This chapter presents the various sources of neutrons that are important in nondestructive measurements. These sources include the key mechanisms of spontaneous fission, neutrons from alpha particle reactions on light elements, and induced fission. The characteristics of neutrons resulting from typical sources are presented. A brief discussion of other neutrons sources, such as those from less common nuclear reactions, cosmic rays, and neutron generators, is included.
