Measurement and Analysis of Radio-frequency Radiation Exposure Level from Different Mobile Base Transceiver Stations in Ajaokuta and Environs, Nigeria

TL;DR

This study assesses radio-frequency radiation levels from mobile base stations in Ajaokuta, Nigeria, finding that exposure levels are below international safety standards despite fluctuations caused by environmental factors.

Contribution

It provides a preliminary measurement and analysis of RF exposure levels from mobile base stations in a specific Nigerian region, highlighting safety compliance.

Findings

RF exposure levels are below ICNIRP safety limits.

Radiation levels fluctuate due to environmental interference.

Measurements were taken within 125 meters of base stations.

Abstract

We present the result of a preliminary assessment of radio-frequency radiation exposure from selected mobile base stations in Ajaokuta environs. The Power density of RF radiation within a radial distance of 125m was measured. Although values fluctuated due to the influence of other factors, including wave interference from other electromagnetic sources around reference base stations, we show from analysis that radiation exposure level is below the standard limit (4.5W/sqm for 900MHz and 9W/sqm for 18000MHz) set by the International Commission on Non-ionizing Radiation Protection (ICNIRP) and other regulatory agencies.
