[Peculiarities of the neurological status and electroencephalogram in operators of the control unit of nuclear power station].

One hundred and five operators of the control unit of the Kursk nuclear power station (NPS) have been studied: 45 people after the shift (main group) and 60 - in the day off. The shift was found to exert a significant influence on the functional state of the nervous system promoting the development or aggravation of autonomous dysfunction. In some cases, it causes an elevation of blood pressure to the level of risk for cerebral vascular disease. The effect of shift on the cerebral bioelectric activity of NPS operators manifests itself in the decrease of percentage of unchanged EEG, increase of alpha-rhythm spectral power density in the parietal leads and theta-rhythm in the posterior temporal and parietal leads. These changes may be caused by weariness as well as the effects of adverse factors the operators were exposed to at the NPS. The authors suggest to include the methods of evaluating of autonomous dysfunction and recording of alpha-rhythm spectral power density in the parietal leads and theta-rhythm in the posterior temporal and parietal leads in a special clinical examination of NPS operators.
