Abstract

The measurement of possible presence of radiofrequency (RF) radiations from telecommunication base stations was carried out within Kaduna North Area of Kaduna State, to estimate the maximum level of power density from RF radiations to which the member of the populace within specific radius from the base transceiver station (BTS) are exposed to in relation to the existing guidelines to human exposure. Power density S (µWm-2) measurements were made at interval of 20 m to check the exposure level at public locations from 10 RF antenna sites starting from the foot of each BS to distance (radius) of 100 m using Aaronia Spectran HF-4060 Analyser and the electric field strength E (Vm-1) were calculated. The highest and lowest value obtained from measured mean power densities were 108.27 µWm-2 and 94.74 µWm-2 from a distance of 100 m and 40 m respectively. Also, the highest and lowest average electric field strength were 202.03 (Vm-1) and 188.99 (Vm-1) at 100 m and 40 m respectively. The result obtained, indicates that the measured values were far less than the permissible exposure limits for both workers and the general public as set by the International Commission on Non-ionizing Radiation Protection (ICNIRP). These results shows that the exposure levels in these areas are low and as such will not pose significant health risks to the people living in the study area.

Highlights

Telecommunication devices have become an integral part of our life; providing services that range from phone calls, Bluetooth connections, internet connections and information sharing via online media [1]
The typical base transceiver station (BTS) consists of telecommunication mast upon which radio frequency transmitters and receivers are mounted, powered by digital electronic boasters which are installed in shelters within the BTS site
Reference [5] reported that the location of adequate telecommunication masts and residents living in Oshogbo, Nigeria are susceptible to physical, health and environmental problems at certain distances from mast

Summary

INTRODUCTION

Telecommunication devices have become an integral part of our life; providing services that range from phone calls, Bluetooth connections, internet connections and information sharing via online media [1]. Telecommunication is the primary means of transmitting information, resulting to installation of telecommunication mast around residential and office areas which may have negative impacts on the life of people living around such vicinity [2]. The typical BTS consists of telecommunication mast upon which radio frequency transmitters and receivers are mounted, powered by digital electronic boasters which are installed in shelters within the BTS site. Reference [5] reported that the location of adequate telecommunication masts and residents living in Oshogbo, Nigeria are susceptible to physical, health and environmental problems at certain distances from mast. Using a descriptive cross-sectional survey, the health hazards of non-ionizing radiation from telecommunication mast on the exposed community within Kaduna and Lagos metropolis were assessed and presented in [2] and [6]. The GPS was used to observe the latitude and longitude of that particular area were the BTS is located
