ABSTRACT
The comparison (juxtaposition) of the rats and the rabbits organism reactions on the electromagnetic irradiation (1.5 GHz, 300 microW/cm2, non-stop mode, 30 min) by the index of the physiological status indicators and of the blood microelements (ME)--metals concentration is presented. This physiological status indicators display that the mentioned irradiation is an underthreshold effect for central nerve system, which doesn't cause the essential changes on the organism level. In the same time, the reliable blood microelements-metals concentration shifts are established. And this let us suppose the ME-indicator as the most informative value of an organism reaction on the electromagnetic irradiations corresponding to the underthreshold effects for the central nerve system.
