There was a study of the health status (with emphasis on psychoneurological status) of crew on military helicopters and aircraft before and after the execution of works on liquidation of consequences of the Chernobyl disaster in 1986, and received a radiation dose of 226 ± 6 mGy. We studied the results of a poll of the liquidators for the purpose of studying their quality of life 10 years after the accident. The obtained data were compared with the results of radiobiological experiments on animals irradiated at doses comparable to that received by the liquidators. The results of the study concluded that, in assessing psychoneurological status of the liquidators of radiation accidents, it is necessary to take into account the initial state of their health and the whole complex of adverse factors of the Chernobyl accident, and not just the external exposure dose. The main measures of prevention of psychoneurological disorders in liquidators should become: a professional selection of volunteers, who know the basics of radiobiology; professional medical-psychological service; the creation of appropriate socio-hygienic conditions and proportional to the risk faced by the liquidators and their families; reducing the level the harmful and dangerous work-related factors of flight operations, as well as prevention (and it seems important) incorporation into the body of long-lived radionuclides.
