Mobile phones cause honeybees to emit stress signals at radiation levels typical of normal phone use, suggesting biological effects below heating thresholds.

Plain English Summary

Summary written for general audiences

Researchers placed active mobile phones near honeybee colonies and recorded the bees' sounds to see if cell phone radiation affected their behavior. They found that phones operating at 900 MHz caused bees to produce 'worker piping' signals, which normally indicate either preparation for swarming or that the colony is under stress. This suggests that cell phone radiation can disrupt normal bee communication and behavior patterns.

Why This Matters

This study adds to growing evidence that wireless radiation affects living systems beyond just heating tissue. The fact that honeybees respond to cell phone radiation at typical operating levels (SAR values of 0.271 to 0.98 W/kg) is particularly significant because bees are crucial pollinators whose declining populations threaten food security. The worker piping response indicates the bees perceived the radiation as a threat or disturbance, triggering stress behaviors normally reserved for colony emergencies. While this research focuses on insects rather than humans, it demonstrates that biological systems can detect and respond to RF radiation at power levels well below current safety standards, which are based solely on preventing tissue heating.
