Mobile phones emit significant radiation even in standby mode, creating continuous exposure that most health studies don't account for.

Plain English Summary

Summary written for general audiences

Researchers measured radiation from people's phones while traveling, comparing phones turned off versus standby mode. They found phones constantly emit radiation even when not in use, with car exposure levels orders of magnitude higher than with phones off, challenging assumptions about phone radiation safety.

Why This Matters

This research reveals a critical blind spot in how we understand mobile phone radiation exposure. While most people focus on radiation during calls, this study demonstrates that phones emit significant RF-EMF even in standby mode due to location updates with cell towers. The measured exposure levels of up to 1.19 mW/m² during train rides represent meaningful radiation doses that accumulate throughout the day. What makes this particularly concerning is that most epidemiological studies examining phone health effects only consider talk time, potentially missing a major source of exposure. The science demonstrates that your phone is actively communicating with cell towers whenever it's powered on, creating continuous radiation exposure that varies dramatically based on your environment and movement patterns.
