The article presents the investigation results of the electromagnetic field biological effects on adrenal glands functional activity in the rats. The electromagnetic field exposure levels were typical electromagnetic fields of portable radios (walkie-talkies). Experiments were carried out on laboratory male rats. Experimental groups were exposured in a transverse electromagnetic wave cell - TEM cell. Sham animal groups were in similar conditions, but without electromagnetic field exposure. The exposure of experimental animals was carried out in three series (12 rats for each group) for three levels of the electric field strength such as 15; 25 and 35 V/m. Gluco-corticoid and mineral-corticoids adrenal functions were assessed by determining the corticosterone and of Na+ and K+ levels in daily urinary excretion. The animal specific absorption rate evaluations were calculated by using the program SEMCAD X v.14 and experimentally in the TEM cell. The dependences of the excretion of corticosterone and electrolytes on the specific absorption rate and exposure time, which indicate that for small values of electromagnetic energy absorption is stimulation of the adrenal glands functional activity, alternating with depression by specific absorption rate increasing.
