Plain English Summary
Italian researchers exposed immune cells from young and elderly people to cell phone radiation levels. They found radiation reduced CD95 (a key immune protein) only in older adults' cells, not younger ones, suggesting aging may increase vulnerability to radiofrequency effects on immune function.
Why This Matters
This study reveals a troubling vulnerability that safety standards completely ignore: age-dependent sensitivity to radiofrequency radiation. The science demonstrates that older adults' immune systems respond differently to the same RF exposure that leaves younger immune cells unaffected. The 2 W/kg SAR used here matches current phone exposure limits, meaning this immune disruption occurs at supposedly 'safe' levels. What makes this particularly concerning is that CD95 plays a critical role in immune system regulation - when this protein is downregulated, it can impair the body's ability to eliminate damaged or infected cells. The reality is that our one-size-fits-all safety standards are based on preventing heating effects in healthy young adults, yet this research shows biological effects vary dramatically with age. You don't have to accept that current limits protect everyone equally when the evidence clearly shows they don't.
Exposure Details
- SAR
- 2 W/kg
- Source/Device
- 1,800 MHz
Exposure Context
This study used 2 W/kg for SAR (device absorption):
- 5x above the Building Biology guideline of 0.4 W/kg
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
To study the possible RF effects on human lymphocyte activation, we analyzed CD25, CD95, CD28 molecules in unstimulated and stimulated CD4+ e CD8+ T cells in vitro.
Peripheral blood mononuclear cells (PBMCs) from young and elderly donors were exposed or sham-expose...
No significant changes in the percentage of these cell subsets were found between exposed and sham-e...
This age-related result is noteworthy given the importance of a such molecule in regulation of the immune response.
