Cell phone radiation at typical exposure levels didn't impair mouse immune system function, suggesting minimal risk to human immunity.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to cell phone radiation (900 MHz GSM) for 2 hours daily over 1-4 weeks to see if it would affect their immune system cells in the spleen. They found no significant changes in the numbers or types of immune cells, and the cells responded normally when stimulated. The study concluded that cell phone radiation at these levels is unlikely to cause clinically relevant immune system problems.

Study Details

The aim of this study was to evaluate whether daily whole-body exposure to 900 MHz GSM-modulated radiation could affect spleen lymphocytes.

This suggests that the immune system might have adapted to RF radiation as it does with other stressing agents. All together, our in vivo data indicate that the T- and B-cell compartments were not substantially affected by exposure to RF radiation and that a clinically relevant effect of RF radiation on the immune system is unlikely to occur.

Quick Questions About This Study

No, 900 MHz GSM radiation did not significantly affect mouse spleen immune cells. A 2003 study exposed mice to cell phone radiation for 2 hours daily over 1-4 weeks and found no changes in immune cell numbers, types, or normal responses when stimulated.
Two hours of daily 900 MHz radiation exposure did not damage T cells in mice. The study found T-cell numbers, CD4 and CD8 subpopulations, and their ability to proliferate and produce cytokines remained normal after 1-4 weeks of exposure.
No, 1-2 W/kg SAR exposure did not weaken B cell function in mice. B cells maintained normal numbers and responded normally to stimulation, showing no clinically relevant immune system impairment from cell phone radiation at these power levels.
IFN-gamma production temporarily increased after 1 week of 900 MHz exposure at 1-2 W/kg, but this effect disappeared with longer exposure periods of 2-4 weeks, suggesting the immune system adapted to the radiation.
Four weeks of GSM radiation exposure is unlikely to be clinically dangerous for immunity. The study concluded that T and B cell compartments were not substantially affected and clinically relevant immune system effects are unlikely to occur.
