Evaluation of Population Exposure to Radiofrequency Fields in Microenvironments in the Cities of Lima, Cusco and Pucallpa in Per�, Using a Personal Exposimeter

Abstract

Overview

The objective of this study was to evaluate radiofrequency (RF) field exposure in the microenvironments of Cuzco, Lima, and Pucallpa using personal exposimeters. A literature review was conducted, followed by the selection of 95 urban microenvironments across the three cities. The exposimeter and proprietary software were tested for data collection and processing.

Methodology

• Urban microenvironments were defined and selected (95 in total).
• Exposimeters were used for RF measurements.
• In total, 1,900 measurements were collected across the three cities.
• Electric field strength was measured in each environment.
• Data processed to obtain exposure quotients based on ICNIRP 1998 guidelines.

Findings

• Maximum electric field: 2.531 V/m.
• Minimum electric field: 0.063 V/m.
• Average electric field: 0.521 V/m.
• Maximum exposure quotient: 0.747% of ICNIRP limit.
• Average exposure quotient: 0.033% of ICNIRP limit.
• Base stations were the largest contributors to exposure.
• Broadcasting services were the second largest contributors.
• Mobile phone handsets contributed far less than base stations.

Conclusion

All measured RF exposures were well below international safety limits set by the ICNIRP. Nonetheless, the study demonstrates detectable population exposure in urban environments, primarily from base stations and broadcasting services. Continued monitoring is important due to the established links between electromagnetic field exposure and potential health risks, as recognized in international safety standards and public health discussions.
