Global System for Mobile Communication (GSM) technology is one of the fastest growing
technologies and most demanding application all over the world. But the health implication of its equipment used or
installed in residential area has become subject debate among Nigerian. This work, made an attempt to determine the
safety distance for installing GSM mast in residential area by measuring power density radiated from the foot of the
GSM mast at different distances; 10m, 15m, 20m, 25m, 30m, 35m, 40m, 45m and 50m. Fuzzy logic technique was
used to forecast power density measured from the GSM mast as 38.9μW/m2, 9.26μW/m2, 9.30μW/m2, 9.24μW/m2,
2.47μW/m2, 2.47μW/m2, 2.38μW/m2, 2.37μW/m2 and 2.36e-6μW/m2. Specific Absorption Rate (SAR) is computed
as 1.09e-4W/Kg, 2.60e-5W/Kg, 2.61e-5W/Kg, 2.62e-5W/kg, 6.94e-6W/Kg, 6.69e-6W/Kg, 6.66e-6/Kg and 6.63e-6W/Kg
from the forecasted power density respectively. The calculated SAR is compared with the standard SAR values, for
localize and whole part of the body (0.08Kg/W and 2.00Kg/W) given by the International Commission on Non –
Ionizing Radiation Protection (ICNIRP) and found to be far below recommended level. This work also, suggested
that, 10m is a good distance for installing GSM mast away from residential areas.
