Abstract
The ever-increasing number of mobile telecommunication base station as a result of increasing demand for broadband applications has raised a growing concern and worry over the health implications and safety of the radiations from these base stations by the resident of Ekiti State and Nigeria in Nigeria. Measurement of radio frequency was conducted in this research in order to study the electromagnetic field radiation level in Ekiti State Nigeria. Investigation was conducted with the four available mobile operators with the three sub-frequency band viz 900 MHz, 1800 MHz and 2100 MHz. The power density of radio frequency radiation was estimated through measurement with the aid of A 3-Axis RF Radiation Strength Meter TM-196 and Handheld Spectrum Analyzer Model NA-773, 144/430. The peak and average power density was computed using the method of theoretical calculation and the safety distance from the antennas were estimated. The measured and the calculated values were compared with the international commission on non-ionizing radiation protection (ICNIRP) standard for public and occupational exposure level. Results show that the radiations from the base stations adheres to the standard provided by ICNIRP

Summary
The recent advances in mobile communication has led to increased broadband applications [1,2,3,4]. In [18], measurement was conducted around the base station of some mobile stations and in [19,20,21], several measurements were conducted in Sweden in a bid to confirm the safety from these radiations All these were conducted outside the region of concern and there are known information about the adherence of the network operators to the limit set by ICNIRP and such nothing can be said about the safety of the dwellers from the RF radiations. In this experiment three locations in Ekiti state were selected representing the urban, suburban and rural areas in Ekiti State Nigeria to study the RF radiation from the erected base stations. Measurements of E-field strength or power density were conducted in Ado-Ekiti; Ifaki-Ekiti, and Iye-Ekiti from base station operation at 900, 1800, and 2100 MHz respectively
