Measurements were made with a calibrated hand held spectrum analyzer 200m away from 271 base stations, at 1.2m to the ground level. The maximum GSM 900 signal power density was 139.63&amp;amp;mu;Wm2 in Lagos, 162.49&amp;amp;mu;Wm2 in Ibadan and 5411.26&amp;amp;mu;Wm2 in Abuja. Also, the maximum GSM 1800 signal power density was 296.82&amp;amp;mu;Wm2 in Lagos, 116.82&amp;amp;mu;Wm2 in Ibadan and 1263.00&amp;amp;mu;Wm2 in Abuja. The level of power density of GSM 900 and GSM 1800 signals in the cities of Lagos, Ibadan and Abuja are far less than the recommended value of 4.5Wm2 for GSM 900 and 9.0 Wm2 for GSM 1800 by the ICNRP guideline. It can be concluded that exposure to GSM signals in these cities cannot contribute to the health detriments caused by thermal effects of radiofrequency radiation. </abstract> <index>Open Science Index 94, 2014</index> </article>
