Assessment of Radiofrequency Radiation Distribution around Mobile Base Stations in Makurdi, Benue State
Iortile, J.T.; Agba, E.H. - In: International Journal of Natural Sciences Research 2 (2014) 1, pp. 1-4
The radiofrequency field levels of selected MTN and ZAIN base stations in Makurdi were measured using electromagnetic field tester (EMF 827, Lutron). Measurements were done at distances of approximately 5.00, 10.00, 15.00 and 20.00 metres for each base station at the North, South, West, and East...
