Terrain pollution by electromagnetic fields from high voltage aerial power lines

Abstract

Analysis of literature, references to the experimental and theoretical research got possibility to disclose connections between health problems of population and long term expousure of low electromagnetic fields - electrosmog. The energy power of low frequency electromagnetic emission is quite small. But electromagnetic radiation of these frequencies has clearly expressed electric and magnetic fields influencing to the human body and individual organs. The most sensitive is central nervous and neuro endocrine systems. The main sources of electromagnetic fields in living and working environment are household appliance, electricity transmission, transformation and distribution devices. Electromagnetic fields emitted from electric devices propagating in the space under l/r³; l/r² and l/r regulations. It is typical for variation of values of electric and magnetic fields. The value of electromagnetic field parameters is defined by voltage of electric devices, current and positioning of studied point regarding devices. Taking into account country's wide energetic network, high number of electric devices emitting electromagnetic lields to the environment, collected data becoming a significant social meaning and the possibility appears in order to predict the impact values of these fields, providing measures to eliminate them. Due to the physical nature electromagnetic waves emitted by out-door industrial-frequency electric devices propagating quite long distances from their sources. This study examining the circumstances which are determining the extent and limits of electrosmog.[...]
