Monitoring of the Change in Electric Field Strength Levels on Samsun Light Rail System

Abstract

Technological improvements and dense use of wireless systems has led to an increase in exposed electromagnetic radiation (EMR) levels in recent years. The effects of these EMRs on the population have not been completely characterized despite intense research on this topic. For this reason accurate evaluation of EMR levels in the environment have become essential. Therefore, this study aims to determine the electric field strength (E) levels on Samsun Light Rail System which can board around 90.000 passengers per day. To reach this goal; extensive E measurements were conducted on trams during the journey of total 36 stops for one week long using PMM 8053 EMR meter, and the E with a sampling period of 1 second was recorded. It is seen from the measurement results that the highest E is 5.44 V/m while the highest mean E is 0.40 V/m. Furthermore, contribution of E sources in total E determined on the basis of band selective measurements via SRM 3006 EMR meter, and the main E source is decided as cellular systems. In addition to that, the signal strengths of three existing operators for cellular systems were measured by using "NetMonitor" application.
