Evaluation of Population Exposure to Radiofrequency Fields in Microenvironments in the Cities of Lima, Cusco and Pucallpa in Perú, Using a Personal Exposimeter. 2024 IEEE XXXI International Conference on Electronics, Electrical Engineering and Computing (INTERCON), Lima, Peru, 2024, pp. 1-8, doi: 10.1109/INTERCON63140.2024.10833492. Abstract The objective of this study was to make an evaluation 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 that of mobile phone base stations. ieeexplore.ieee.org

Main findings

Using a personal exposimeter, 1900 measurements across 95 microenvironments in Lima, Cusco, and Pucallpa found electric field levels ranging from 0.063 to 2.531 V/m (overall mean 0.521 V/m). Exposure quotients based on ICNIRP 1998 limits were low (maximum 0.747%, mean 0.033%), and all measurements were reported as well below international limits; the largest contributors were mobile phone base stations, followed by broadcasting services, with handset exposure well below base stations.

Outcomes measured

• Electric field strength (V/m) in microenvironments
• Exposure quotient relative to ICNIRP 1998 limits
• Relative contribution of sources/services to total exposure

Limitations

• Frequency bands measured are not specified in the abstract
• Measurement protocol details (timing, duration per measurement, routes, representativeness) are not provided
• No population/participant characteristics described (personal exposimeter deployment details unclear)
• ICNIRP 1998 limits used; comparison to newer guidelines not discussed in abstract

Suggested hubs

• who-icnirp (0.6)
  Exposure quotients are explicitly calculated against ICNIRP 1998 limits.
