Two-hour exposure to 3G cell phone radiation did not activate brain immune cells at power levels up to 2.0 W/kg.

Plain English Summary

Summary written for general audiences

Japanese researchers exposed rat brain immune cells called microglia to 1950 MHz cell phone radiation for 2 hours at various power levels, then monitored the cells for signs of activation or inflammation. They found no significant differences between exposed and unexposed cells in terms of immune markers or inflammatory proteins. This suggests that short-term exposure to 3G cell phone frequencies at typical power levels does not trigger immune responses in brain cells.

Study Details

To examine any biological effects on the central nervous system (CNS) induced by 1950 MHz modulation signals, which are controlled by the International Mobile Telecommunication-2000 (IMT-2000) cellular system, we investigated the effect of RF fields on microglial cells in the brain.

We assessed functional changes in microglial cells by examining changes in immune reaction-related m...

Results showed that the percentage of cells positive for major histocompatibility complex (MHC) clas...

These findings suggest that exposure to RF fields up to 2 W/kg does not activate microglial cells in vitro.
