[Clinical characteristics of radiation sickness with radiation exposure of different parts of the human body].

The clinical picture of radiation sickness of 139 radiological patients exposed to local irradiation of the head, chest and stomach with efficient doses of 210 rad was examined. It was found that at fractionated local irradiations the clinical symptom-complex of radiation sickness was identical to that seen as a result of total-body irradiation. During head irradiation the major symptom was headache and during stomach irradiation nausea. The severity level of radiation damage measured with respect to the clinical symptom-complex as a whole with the aid of the bioinformation model was similar during irradiations of the head and stomach much higher during irradiation of the chest. During head and stomach irradiations the severity level of radiation damage was proportional to the efficient dose. During chest irradiation there was no correlation between the severity level and the exposure to doses of 210 rad.
