Gastrointestinal system radiation injury

In most organs and tissues the injury and the underlying mechanism for that injury are complex and may involve a combination of events. The extent and severity of this tissue injury are dependent upon the radiosensitivity of the various cell types in that organ system. Rubin and Casarett (1968) describe and schematically display the events following radiation in several organ system types. These include a rapid renewal system, such as the gastrointestinal mucosa a slow renewal system, such as the pulmonary epithelium and a nonrenewal system, such as neural or muscle tissue. In the...
