Combined radiation lesions

Problems of combined radiation lesions resulted from intakes of nuclear fission products into the organism are discussed. It is shown that external and internal radiation dose rates determine the gravity of radiation sickness and its specific clinical course after combined radiation lesions, external radiation affecting the organism shortly after the exposure and internal radiation producing a considerable effect in remote time after the radiation effect. It is noted that combined radiation lesions increase the intensity of biochemical disorders, one of the reasons being the radiation injury of liver and thyroid. It is emphasized that internal radiation creates preconditions for decreasing organism stability to exogenous and endogenous infections
