ASSESSMENT OF RADIOFREQUENCY RADIATION WITHIN THE VICINITY OF SOME GSM BASE STATIONS IN GHANA: A FOLLOW-UP

Abstract

Abstract A follow-up of radiofrequency (RF) electromagnetic radiation safety survey at public access points had been carried out in 46 towns on 76 Global Systems for Mobile Communications and Universal Mobile Telecommunication System cell sites in two major cities in Ghana. The core objective was to determine the RF field levels in residential areas, schools and marketplaces and compare the measured results with the guidelines set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Measurements were made with calibrated log-periodic antenna coupled with a spectrum analyzer. The results obtained varied from 0.0008 to 182 mW m −2, which generally shows compliance with the ICNIRP reference levels. The highest value was 1.39 % of the reference.
