[The structural-dynamic characteristics of the reactive psychoses in persons subjected to ionizing radiation exposure as a result of the accident at the Chernobyl Atomic Electric Power Station].

Thirty case histories were examined of patients who participated in liquidation of sequels of the Chernobyl disaster or inhabiting contaminated territory during the first months after the catastrophe. Of them eleven showed reactive states accompanied by psychopathological disorders. The psychotic disorders in these subjects were simple and concrete by their clinical course, developed mainly during the first 2-4 months after the disaster when the stressogeneity was maximal. This conclusion is confirmed by the fact that of 148 persons subjected to radiation effects and treated at a Kiev Mental hospital from 1986 through 1990 reactive psychoses were observed only in 11 cases.
