Abstract

Abstract Overview

In recent years, due to the surge in wireless technology, the exposure to radiofrequency electromagnetic fields (RF-EMF) has dramatically increased, raising public health concerns. The introduction of personal exposimeters has enhanced research opportunities in this field.

Study Objectives

• The main aim was to characterize personal exposure to RF-EMF in Albacete (population: 166,000, SE Spain).
• Assess how sharing results with study participants alters their risk perceptions regarding RF-EMF.

Methodology

Measurements were taken with a Satimo EME SPY 140 exposimeter for 24 hours at 10-second intervals across various city environments. 75 volunteers were involved, and 35 of these completed a post-study risk perception questionnaire.

Findings

The average total exposure was 37.7 μW/m2. Notable differences were observed across different times and environments, with the highest exposure from DECT phones (50.2%). After the study, 54% of participants perceived RF-EMF to be safer than before, with only 9% fearing their effects as compared to 39% in a control group.

Conclusion

The study indicates that personal exposure levels are below ICNIRP guidelines, but the presence of a significant source from DECT highlights an under-recognized contribution to RF-EMF exposure. Sharing detailed exposure data can effectively reduce public fears.
