DETERMINATION OF THE ELECTROMAGNETIC POLLUTION IN LOCAL SCHOOL INDOOR AND OUTDOOR ENVIRONMENTS

Abstract

This paper presents and analyses combining measurement of the RF and ELF bands of the EMF's from the external sources located around the 24 schools in Nilufer / Bursa, TURKEY throughout 2013 - 2015. The study has been conducted in three steps. In the first step, a circular zone with constant diameter which take the school building as its center and might include base-stations and high-voltage transmission lines has been investigated. The number of EMF sources have been determined and they have been classified their source and band types. Then, in the second step, RF and ELF bands of the electromagnetic fields have been measured in different frequency bands. Then at the last stage, measurements at the some locations have been repeated and validation of the results have been checked. During measurements, Narda SRM 3006 spectrum analyzer, Narda NBM 550 broadband field meter and Narda ELT 400 survey meter have been used. Finally the measurement results have been provided in graphs and compared with the domestic and international exposure limits.
