Measurements of RF/MW Radiation Emitted from Selected Mobile-Phone Base-Stations in Sudan

摘要

Scattering of mobile-phone base-stations within populated areas is a source of some misscomfortablenessto many people. As there is no one agreed on safety level for the MPE for RF/MWallover the world, measurements of radiation emitted from base-stations is a necessity. In this work wescreened out some mobile-phone base-stations inside and outside Khartoum city in Sudan.Measurements were done indoor and outdoor to maximum horizontal distance of about 300 m from thebase of the base-stations. Results obtained were then compared to the maximum and minimum MPEvalues admitted in different countries in the world. The maximum MPE value (i.e- 0.57 mW/cm2)consider only the thermal effects of the RF/MW, while other values tend to reduce the exposure limitsto as minimum as possible for safety considerations (considering non-thermal effects). Some of thevalues obtained were consistent with some reported biological effects. We recommended the removalof some base-stations from sensitive areas like schools, kindergardens, hostels, hospitals, etc.
