5G Phones Emit Higher Radiation in Rural Areas, Study Finds

0 3

Increased exposure is not due to 5G cell towers but rather mobile devices working harder

A new study reveals that 5G phone users in rural areas experience nearly double the radiation exposure compared to those in cities. The Swiss Tropical and Public Health Institute (Swiss TPH) tracked radiofrequency electromagnetic field (RF-EMF) exposure in two cities and three rural towns, discovering that rural users were exposed to an average of 29 mW/sq-m while uploading data, exceeding the World Health Organization’s (WHO) recommended safety threshold of 10 mW/sq-m. This increased exposure is not due to 5G cell towers but rather mobile devices working harder to send signals in areas with fewer base stations.

Lead researcher Adriana Fernandes Veludo explained that lower base station density forces mobile phones to emit stronger signals, leading to higher personal radiation exposure despite lower environmental exposure. The study also suggests that real-world exposure could be even higher, as radiation measurements were taken from devices positioned 30 cm (11.8 inches) away, whereas people typically hold phones closer to their bodies, potentially increasing exposure up to 10 times.

Despite Europe considering 29 mW/sq-m high, the U.S. Federal Communications Commission (FCC) permits exposure up to 10,000 mW/sq-m, a far more lenient standard. While the study does not assess health risks, it provides valuable insights into 5G radiation exposure. Researchers used portable tracking devices to measure RF-EMF levels across different environments, including schools, parks, and public transit. Their findings, published in Environmental Research, highlight the need for further research on mobile radiation exposure, particularly in rural areas.
