Gastrointestinal syndrome (GI syndrome) is one of the three classic sub-syndromes of acute radiation syndrome, alongside the hematopoietic and neurovascular syndromes, and represents a more severe stage of radiation injury than the hematopoietic syndrome alone. It often follows absorbed radiation doses of 6 to 30 grays (600 to 3,000 rad). Its signs and symptoms include nausea, vomiting, loss of appetite, and abdominal pain; vomiting within one to two hours of exposure is itself a marker for whole-body doses in the fatal range above 4 grays (400 rad). Without exotic treatment such as a bone marrow transplant, death at this dose level is common, generally caused more by infection than by gastrointestinal dysfunction itself.

Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time.
Signs and symptoms section
This syndrome often follows absorbed doses of 6-30 grays (600-3,000 rad). The signs and symptoms of this form of radiation injury include nausea, vomiting, loss of appetite, and abdominal pain. Vomiting in this time-frame (1-2h post-exposure) is a marker for whole-body exposures that are in the fatal range above 4 grays (400 rad). Without exotic treatment such as bone marrow transplant, death with this dose is common, due generally more to infection than gastrointestinal dysfunction.
