Assessment of harmful effects of RF fields in the vicinity of the antenna of digital radio modem

Abstract

The paper points to the necessity of measuring the electric field in the vicinity of the antenna of digital radio modem and its influence on the human organism. The modem is an integral communication part of the portable test system, which is used to set the system parameters and for wireless data gathering and data exchange with main monitoring system in the rail. The need for measuring of the electric RF field was due to the necessity of assessing its impact on the operator considering the short distance between the operator and antenna of the portable test system. Impact assessment was carried out on the basis of Regulations in the Republic of Serbia (safety requirements regarding the exposure of citizens) and on the basis of EU Directive (safety requirements regarding the exposure of workers).
