Resumen

The objective of this study was to make an evalu-ation of radiofrequency fields in microenvironments of Cuzco, Lima and Pucallpa using personal exposimeters. To carried it out a literature review was first made, then the urban environ-ments were defined, and 95 microenvironments were selected in the three cities. Subsequently, the exposimeter including the proprietary software for data processing was tested. In total, 1900 measurements of the main telecommunications services were carried out. The electric field was measured for each environment, with a maximum of 2.531 V/m, a minimum of 0.063 V/m and an average of 0.521 V/m for all measurements combined. Based on the ICNIRP 1998 limits, exposure quotients were also obtained for all the measurements combined and for the measurements in each city considering outdoor and indoor measurements, different types of environments and by main frequency bands. For all measurements combined, the maximum exposure quotient was 0.747% and the average was 0.033%. All measurements made were well below international limits, the largest contributors to total exposure were mobile phone base stations, the second largest were broadcasting services, and mobile phone handsets exposure was well below than that of mobile phone base stations.
