PSYCHOPHYSIOLOGICAL FEATURES OF RADIATION RISK PERCEPTION

M. V. Gresko, I. V. Perchuk..

OBJECTIVE: to determine the subjective and psychophysiological characteristics of the perception of radiation risk,to identify destructive individual-typological personality traits, as well as factors that can be the basis of psycho-logical compensation for victims of various radiation disasters and accidents.

OBJECT AND METHOD: A comparative analysis of psychometric and neurophysiological parameters of hypertrophiedperception of radiation risk in the following groups was carried out: liquidators (clean-up workers) of the conse-quences of the Chornobyl accident and evacuees from the Chornobyl exclusion zone (CEZ) - 317 people total, par-ticipants in the anti-terrorist operation (ATO) - 101 people, and control group - 85 people. We used psychodiagnos-tic and neurophysiological (computerized electroencephalography) techniques.

RESULTS: In the groups of liquidators and evacuees from CEZ there are significantly more people with hypertrophiedperception of radiation risk compared to the control group and the comparison group (liquidators - 71.88 %, liqui-dators-evacuees - 80.0 %, evacuees 76.92 %, ATO participants - 33.78 %, control group - 35.0 %). Among therespondents with hypertrophied perception of radiation risk radiation factors, and, most of all, diseases associatedwith ionizing radiation, hold the first rank places among 31 evaluated factors in all groups. The respondents withadequate perception of the radiation risk are primarily concerned about social stress and environmental factors.Correlation analysis showed that there are no correlation between hypertrophied perception of radiation risk andactual documented radiation dose. Hypertrophied perception depends on gender, level of education, family incomeand level of knowledge about ionizing radiation. It affects perception of one's health, makes you feel helpless,increase the level of distress from the Chornobyl disaster and the Fukushima-1 disaster in Japan, and is also associ-ated with the Revolution of Dignity. Hypertrophied perception of radiation risk contributes to disorders of psycho-somatic health and deformation of personality traits. Comparative analysis of the parameters of bioelectrical activ-ity of the brain of persons with hypertrophied perception of the radiation threat showed an increase in brain's delta-,theta- and beta- activity with suppression of alpha-activity and dominant frequency.

CONCLUSIONS: In all examined groups a significant percentage of people with hypertrophied perception wererevealed. The key role in the process of perception of a radiation risk is played not by the real danger of the situa-tion and the documented dose of radiation, but by its perception and awareness. Hypertrophied perception of theradiation risk contributes to psychosomatic health disorders and deformation of personality traits, which is con-firmed by neurophysiological studies.
