It is known that the effects of high-dose radiation differ from the effects of exposure to low-intensity radiation at low doses. Low-dose radiation has probabilistic, mediated and non-linear dose-response; systemic response of an organism; differences in the effects of irradiation of different power in equal doses, at local and general exposures, between the effects obtained in cell cultures and isolated from the irradiated organism, late radiation effect; modifying effect of the physiological state of an organism. These effects correspond to the known signs of impact of factors on the body by means of signal & information mechanisms. Signal perception allows forming a response to content of the signal only, but not to the characteristics of material carrier (energy), that’s why understanding of the absorbed dose, free radical processes are not applicable in the area of action of small doses. How can ionizing radiation cause the death of organisms via signal impact, and not energy one? According to the information theory the main cause of death of any system is termination of intersystem connections. It happens when the leading control mechanism (CNS for higher organisms) loses its stability. It is well known that a signal can be perceived, recoded, transmitted, processed, stored, extracted or erased from memory. Assimilation and processing of information has a profound effect on formation processes of an organism response to signals, including electromagnetic ones. Integral processing and storage of information is carried out in certain brain structures. The redundant flow of signal information into these structures leads to impossibility of solving information problems with sufficient speed; all this causes the disruption of control structures of an organism and total disadjustment. In these conditions, a system gets more stress and even negligible impacts can provoke the loss of its stability and destruction. Electrophysiological and biochemical studies have confirmed that post radial effects in the cardiovascular system were caused by the lower efficiency of regulatory CNS influences. These data allow us to conclude that the biomedical consequences caused by low-intensity ionizing radiation at law doses on the body are determined by exorbitant intensification of information processes in the CNS. The possibility of correcting of ionizing radiation exposure on the body using of EHF-radiation and alternating magnetic fields was shown.
