[Changes in arterial elasticity after high-frequency electromagnetic field irradiation]

Results are reported and discussed of elastographic studies in human subjects, irradiated with electromagnetic field, 66 kH frequency and 40 V/m and 0.14 A/m intensities, i.e. with low intensity electric field (borderline normal values for a whole working day). Two types of response to electric field exposure were recorded, depending on the baseline state of the arteries. The changes in the functional state of the vascular system are characterized by signs of hypotonia and vascular tonus changes. The technique of indirect determination of blood vessel elasticity shows a high sensitivity in these weak electromagnetic fildes and may be used in studies on human subjects, professionally exposed to high intensity fields.
