Plain English Summary
Scientists exposed infection-fighting white blood cells to 900-MHz cell phone radiation. The RF exposure made cells move 50% faster and in wrong directions, away from infection sites they should target. This immune system disruption occurred within minutes at non-heating power levels.
Why This Matters
This study reveals a concerning disruption to one of your immune system's most basic functions. Neutrophils are your body's first responders to infection and injury, and their ability to navigate toward trouble spots is critical for proper immune response. The fact that cell phone-level RF radiation can scramble these cellular navigation systems within minutes suggests our wireless devices may be interfering with immune function in ways we're only beginning to understand. The 0.4 V/m exposure level used here is well within the range you experience when using a cell phone or being near wireless devices. What makes this particularly significant is that the effect occurred without any measurable heating - contradicting the wireless industry's long-held position that only thermal effects from RF radiation matter for human health.

Study Details
The effects of radio frequency (RF) fields on the ability of human neutrophils to follow concentration gradients of Cyclic Adenosine 3', 5'-Monophosphate (C-AMP) are reported.
Blood from healthy adult donors was exposed in vitro to different temperatures and 900-MHz RF field ...
It was observed that the neutrophils' speed increased with increasing temperatures from 35 degrees t...
The average time for the neutrophils to respond to the effect of RF radiation was about 2.5 min.
