Radio Frequency Electromagnetic Exposure: A Public Safety Assessment

Nowadays, with the impressive development of cellular networks and other wireless communication technologies, the public concerns about possible health effects of exposure to electromagnetic radiations are increased. In this paper, we investigate some radio frequency (RF) exposure levels measured in the urban areas. These measurements include all RF radiations of various electromagnetic wave sources including those from broadcasting stations to cellular base stations. The exposure levels are incident power density values measured during 18 months at 930 locations distributed over 7 major cities of Iran. These results are compared with the relevant guidelines of non-ionizing radiation given in the Iran national standard no. 8567, to confirm that the measured radiation exposure levels are satisfactorily below the defined limits.
