Abstract

A tool study of the electromagnetic fields of the industrial frequency and radio-frequency range in Murino of Leningrad oblast was undertaken. Steady excesses of the admissible levels of tension on the borders of a sanitary rupture of a high-voltage line of 330 kV were revealed. Excesses of admissible levels of magnetic induction and in the radio-frequency range of the energy stream density are not revealed. It is established that the difference of values of the electric field strength 1.8 m from a surface and at a height of 72 m reaches 1–2 orders of magnitude, which can be explained only with the role of grounding to Earth’s surface. Considerable divergences of the settlement and measured values of tension and magnetic induction are revealed, which means insufficiently correct account when calculating the electrophysical properties of air. The detailed cards of the density of a stream of energy showing a difficult, but steady picture of the distribution of values are created. Some elements of the territorial structure of electromagnetic fields of the radio-frequency range are fragments of rings around base stations of cellular communication, and the auras dated for certain houses are revealed.
