Two phenomena, decrease in strength of the vascular wall and decreased amount of thrombocytes in blood, must coincide for manifestation of the hemorrhagic syndrome. Either almost simultaneous injury to the vascular wall and thrombocyte function (with acute irradiation) or dissociation of these two processes (with long-term irradiation) may be observed, depending on the radiation dose. Chronic exposure at low (subliminal) dose rates does not elicit hemorrhagic manifestations or death of rats due to pathological bleeding.
