Plain English Summary
Researchers exposed human immune cells to 900 MHz microwave radiation (similar to GSM cell phone signals) at very low power levels and found that the radiation significantly increased immune cell activity. The exposed cells showed stronger responses to immune stimulants compared to unexposed control cells. This suggests that even weak microwave radiation can alter how our immune system functions.
Why This Matters
This study adds important evidence to our understanding of how radiofrequency radiation affects immune function, even at extremely low exposure levels. The SAR of 0.024 W/kg used here is roughly 48 times lower than current regulatory limits for cell phones, yet still produced measurable biological effects. What makes this research particularly significant is that it demonstrates immune system changes can occur during active cell division phases, when cells may be most vulnerable. The findings align with a growing body of research showing that RF radiation can modulate immune responses in ways we're only beginning to understand. While an enhanced immune response might sound beneficial, any artificial stimulation of immune activity raises questions about long-term consequences and the potential for immune system dysregulation.

Where This Falls on the Concern Scale
Study Details
We investigated whether cultured immune cells induced into the active phases of cell cycle (G(1), S) and then exposed to microwaves will also be sensitive to electromagnetic field.

The results suggest that immune activity of responding lymphocytes and monocytes can be additionally intensified by 900 MHz microwaves.
