Electromagnetic Field Chronic Exposure Effects of Cellular Base Stations on Rat Hemopoesis

The results the multifrequency electromagnetic field biological effect studies generated by mobile cellular communication base stations on hematological parameters and cellular composition of the bone marrow are presented. Wistar rats were exposed to electromagnetic field with a total power density 250 μW/cm2 1.8; 2.1; 2.6 GHz and 3.5; 26; 37 GHz, and with a total power density 500 μW/cm2 at 1.8; 2.1; 2.6; 3.5; 26; 37 GHz. Rats exposure was carried out continuously for 4 months, the biological material was taken one month after the termination of exposure. A significant change was found in one of the hematological parameters of exposed rats at frequencies 1.8; 2.1; 2.6 GHz with power density 250 μW/cm2. Statistically significant changes in the bone marrow myelogram of exposed rats were revealed, namely, an increase percentage of stab neutrophils and lymphocytes, a decrease oxyphilic erythroblasts and monocytes in rats after exposure to frequencies 3.5; 26; 37 GHz with 250 μW/cm2, as well as with the sum of all frequencies, i.e. 1.8; 2.1; 2.6; 3.5; 26; 37 GHz with 500 μW/cm2. Other changes in hematological parameters and cellular composition of the bone marrow exposed animals remained within the physiological norm. The detected changes may indicate potential longterm effects of chronic exposure to multifrequency electromagnetic fields of base stations of cellular communication on the hematopoietic system. © 2022, Akademkniga.
