Abstract:
The hypothesis about presence of information character of electromagnetic radiation of a millimeter wave band has found practical application: use of some frequencies for diagnostics and therapeutic influence on the person is authorized. The choice of such frequencies is made on the basis of experimental researches. At the same time there is no full confidence, that the choice of such frequencies is optimum. If to assume presence influence of external radiation on process of ions carry through a membrane at the passive transport, dependent only from presence of a concentration gradient and static membrane potential, and to enter the variable components caused by presence of weak high-frequency indignations of potential and concentration, that, alongside with classical equation Nernst - Planck there is an equation for a variable component of the current, allowing to define boundary frequencies on a equation , where ? the law of change of concentration along thickness of a membrane, mobility and valence of corresponding type of ions, accordingly. It is interesting to note, that practically always boundary frequencies lay in Giga Hertz a range (frequencies above 109 Hz), that should testify to special attention to researches of influence of the microwave of electromagnetic energy on biological objects. Their values depend on size of dielectric permeability of environment, from size of a gradient of concentration and can change in limits from units up to several tens Giga Hertz. The hypothesis offered in the given work defines possible low-frequency boundaries, not stipulating a range of influence of electromagnetic radiation and its interaction with alive systems
