title: [State of hemodynamics, according to radiocardiographic data, in persons working in contact with ionizing radiation sources].
abstract: The presented results illustrate the study of the cardiovascular system by means of radiocardiography conducted in normal individuals working in contact with sources of ionizing radiation. The study includes 51 persons in the test group and 42 in the control group that was similar to the test one in terms of age, sex and type of work performed, with the only exception that these in the control group had no contact with ionizing radiation. Persons working under the effect of ionizing radiation displayed a moderate increase in the stroke and minute index and the circulating blood volume, with the blood flow rate somewhat decelerated. The changes were deeper in those with over 5 years of service, and in those with functional changes in the nervous system, like neurocirculatory dystonia. The moderate level of these reactions and their reversibility permit to interpret them as an adaptative reaction to the effect of low doses of ionizing radiation.
