ARS - Gastrointestinal System

Symptoms in this system are regularly seen at acute doses greater than 600 rads and result from radiation induced damage to the epithelial cells lining the small intestine.  The higher the exposure, the sooner the symptoms of nausea and vomiting develop.  The presence of these symptoms typically overlaps with the drop in cell count described previously.  As a result, this can lead to loss of fluids, electrolytes and opportunistic infections resulting in septicemia.  Persistently high fevers and bloody diarrhea are an ominous signs.  Death occurs within 9-13 days.
