View Original AbstractGSM cell phone signals increased immune cell activity at power levels 80 times below current safety limits.
Plain English Summary
Polish researchers exposed human immune cells to 900 MHz GSM cell phone signals at very low power levels (SAR 0.024 W/kg) and found that the microwave exposure significantly increased immune cell activity. The exposed cells showed stronger responses to immune stimulants and higher activity levels compared to unexposed control cells. This suggests that even low-level cell phone radiation can alter how your immune system functions at the cellular level.
Why This Matters
This study adds important evidence to our understanding of how cell phone radiation affects immune function, even at exposure levels well below current safety limits. The SAR of 0.024 W/kg used here is roughly 80 times lower than the 2 W/kg limit set by the FCC, yet still produced measurable biological changes in immune cells. What makes this research particularly significant is that it demonstrates EMF effects on actively dividing immune cells, which are constantly present in your body as your immune system responds to threats. The finding that microwave exposure can 'intensify' immune activity raises questions about whether chronic low-level exposure from phones and wireless devices might contribute to immune system dysfunction or autoimmune responses over time.

Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
In an earlier study we reported that G(o) phase peripheral blood mononulclear cells (PBMC) exposed to low-level (SAR = 0.18 W/kg) pulse-modulated 1300 MHz microwaves and subsequently cultured, demonstrate changed immune activity (Dabrowski et al., 2003). 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.
