The article highlights the issue of accuracy of determining of the zones of restricted use of the territories along the transmission lines taking into account the magnetic field influence around the wires of transmission line during the passage of electric current. The procedure of establishing of such zones near transmission lines requires a clear substantiation of limits of physical parameters of the electric and magnetic fields` influence of transmission lines on human resources and environment that leads to the establishment of scientifically based boundaries of safe and rational management of land use. The authors` task was the substantiation of a mathematical expression that describes the relationship between the accuracy of determining the radius of dissemination of the magnetic field along the transmission lines and physical parameters of the magnetic field. As a result of the conducted research the formulas for determining the standard deviation (SD) of the radius of dissemination of the magnetic field were presented taking into account the value of magnetic induction, capacity, voltage and amperage that were inherent to the particular transmission line.
