Abstract

This study investigates the radiofrequency radiation levels at selected cellular base stations and evaluated the results against the internationally recommended and accepted levels as well as against the required limit for non-occupational exposure with respect to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) standard for Radio Frequency (RF). The highest Radio Frequency (RF) levels at each base stations were computed as a percentage of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) recommendations in a given and selected environment in Ekiti State. Radio frequency radiation (RF) levels were measured at 15 selected cellular base stations of which 14 were Greenfields and only 1 was Hilltop base station in Ado-Ekiti, Ekiti State, Nigeria. The mobile cellular network operators considered for this investigation are MTN, GLO, AIRTEL, ETISALAT and any other combined network operators on a mast. Detailed measurements of power density of RF radiation were recorded over 2G, 3G and 4G cellular frequency bands at which the cellular network operators transmit in Ekiti State. Measurements were taken at intervals of 5 meters away from base stations up to 260 meters of the prominent populated areas taking into cognizance the direction of antenna used to generate the maximum radiation. At a distance of 5 meters, the highest case of maximum RF exposure at 900 MHz frequency band was 0.0117 W/m^2 which is 0.26% of the ICNIRP maximum public exposure (MPE) limits of the frequency band. At 1800 MHz frequency band, the highest RF exposure recorded was 0.0046 W/m^2, which is 0.05% of the ICNIRP (MPE) limits of the frequency band. The highest RF exposure at 2100 MHz frequency band recorded was 0.0030 W/m^2, which is only 0.03% of ICNIRP (MPE) limit of the frequency band given the highest radiation levels by considering the base stations situated at Ekiti State University (EKSU), Ado-Ekiti, Nigeria. This study reveals that the radiation exposure levels in Ado-Ekiti, Ekiti State, Nigeria emitted by the four mobile cellular network operators are of orders of magnitude below the maximum permitted limits by the local and international regulatory commission and council.
