Abstract—This work is the measurement and analysis of the Radio Frequency (RF) power densities from the Global System for Mobile com- munications (GSM) at some selected points in the Federal University of Agriculture, Abeokuta (FUNAAB), Nigeria, considering 900 MHz and 1800 MHz masts. Measurements were conducted at selected places using Frequency-selective spectrum analyzer (Nokia 6800 Network Drive Tester) to determine the RF Power Densities S, Electric Field Intensities E and the Specific Absorption Rates (SAR). The maximum RF exposure was obtained at COLENG upstairs, with the power densities    3.7 x 10-4 % of the maximum allowable value at 900 MHz and 1.68 x 10-6 % of the maximum exposure level at 1800 MHz. The recorded highest electric field intensities were 75.7 x 10-3V/m and 7.57 x 10-3V/m; 0.18% and 0.013 % of ICNIRP maximum public exposure levels for 900 MHz and 1800 MHz respectively. The highest obtained SAR values were 4.2635 x 10-3 W/kg and 0.06415 x10-3 W/kg; 5.329% and 0.08% of the maximum recommended exposure level for the head region and brain tissue at 900 MHz and 1800 MHz. The results from these studies are useful sources of environmental information and database to the FUNAAB community
