Laboratory brain cells showed no damage from 900 MHz radiation up to 24 hours, but isolated cell studies cannot predict long-term real-world effects.
Plain English Summary
Summary written for general audiences
Swedish researchers exposed brain glial cells (support cells that protect neurons) to 900 MHz radiation at various power levels for up to 24 hours to see if it would trigger inflammatory responses or cellular damage. They found no significant effects on inflammatory markers, cellular proteins, or cell structure at any exposure level tested. The study suggests that short-term exposure to 900 MHz radiation at these levels does not cause detectable damage to these important brain cells in laboratory conditions.
Exposure Information
The study examined exposure from: 900 MHz Duration: 24 hours
Study Details
The aim of the present study was to investigate whether 900 MHz radiation could affect these two different glial cell types in culture by studying markers for damage-related processes in the cells.
Primary cultures enriched in astroglial cells were exposed to 900 MHz microwave radiation in a tempe...
No significant differences could be detected for any of the parameters studied at any time and for a...
Thus this study does not provide evidence for any effect of the microwave radiation used on damage-related factors in glial cells in culture.

Quick Questions About This Study
No, a 2006 Swedish study found that 900 MHz radiation at 3 W/kg SAR caused no detectable damage to brain glial cells after 24 hours of exposure. Researchers found no changes in inflammatory markers, cellular proteins, or cell structure in these important brain support cells.
Research shows 900 MHz microwave radiation does not trigger brain inflammation. A laboratory study exposed brain microglial cells to this frequency for 8 hours and found no increases in inflammatory markers like IL-6 or TNF-alpha, suggesting no inflammatory response occurs.
Exposure to 3 W/kg SAR from 900 MHz radiation showed no effects on astrocytes and microglia in laboratory conditions. Swedish researchers found these brain cells maintained normal protein levels, structure, and function even after extended exposure periods up to 24 hours.
Brain support cells (glial cells) appear resistant to cell phone frequencies based on laboratory research. A 2006 study found that astrocytes and microglia showed no structural damage, protein changes, or activation markers when exposed to 900 MHz radiation at various power levels.
Short-term 900 MHz exposure does not harm cultured brain cells according to controlled laboratory research. Scientists exposed brain glial cells for up to 24 hours and detected no significant changes in cellular damage markers, morphology, or inflammatory responses at any tested exposure level.
