Psychological research was conducted according to the method of Shmishek on 204 volunteers — 1st year students of the State University of Telecommunications, who belonged to the 1—2st group of health. We studied the number of accentuations of the character of a person depen-ding on the exposure time of electromagnetic radiation in the radiofrequency range (EMF RF-range) from computers or mobile phones (smartphones and other gadgets). A statistically significant increase of 45 % was shown in the number of character accentuations from 3 to 6, with an exposure time of 9 to 15 years of EMF RF-range from mobile phones and smartphones. At the same time, the number of people who had up to 2 manifestations of cha-racter accentuations — had an advantage in the group of students with a lower exposure to EMR RF-range from mobile phones and smartphones for 5—8 years. Also, with the help of questionnaires and functional examination of students, when performing orthostatic tests, a positive correlation was found between the formation of vagotonic reactions of the cardiovascular system and the term of exposure to EMF RF-range in years. The prevailing of radiofrequencys from mobile phones was determined in the formation of increased functioning of the parasympathetic nervous system in the examined group of young people (at rxy = +0,962) was determined. Perhaps this correlation also has a pathogenetic significance: with the local form and prolonged exposure to EMR RF-range from mobile phones, they can not only stimulate the vagus nuclei of the medulla oblongata or increase the permeability of the blood-brain barrier, but also change mental processes.
