Estimation of peak power density in the vicinity of cellular base stations and comparison of theoretical values with exposure limits for public, offers the possibility of knowing the safety distance from those antennas. In this paper, we present results of estimations for the peak power density radiated from antennas, by eliminating or not considering reflected waves from different surfaces. This method is used to estimate the peak power density of non ionizing radiation of cellular antennas, installed in 12 regions of Albanian territory by a cellular operator. We have estimated the safety distances from all types of installed antennas, in order to have a clear idea on the safety distances from cellular base station at 900MHz.
