Evaluation of GSM Radiation Power Density in Three Major Cities in Nigeria
نویسندگان
چکیده
The levels of maximum power density of GSM signals in the cities of Lagos, Ibadan and Abuja were studied. 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 139.63μW/m in Lagos, 162.49μW/m in Ibadan and 5411.26μW/m in Abuja. Also, the maximum GSM 1800 signal power density was 296.82μW/m in Lagos, 116.82μW/m in Ibadan and 1263.00μW/m 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 4.5W/m for GSM 900 and 9.0 W/m 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. Keywords—Radiofrequency, power density, radiation exposure, base stations (BTS).
