Three generations of rats showed no brain effects from 20-hour daily cell phone radiation exposure at typical device levels.

Plain English Summary

Summary written for general audiences

Japanese researchers exposed three generations of rats to cell phone signals (2.14 GHz W-CDMA) for 20 hours daily, testing brain function and development across multiple generations. They found no adverse effects on brain function, behavior, or development in any of the three generations studied. This comprehensive multigenerational study suggests that chronic exposure to these specific cell phone frequencies at the tested levels did not cause detectable brain or developmental problems in rats.

Study Details

The present experimental study was carried out with rats to evaluate the effects of whole body exposure to 2.14 GHz band code division multiple access (W‐CDMA) signals for 20 h a day, over three generations.

The average specific absorption rate (SAR, in unit of W/kg) for dams was designed at three levels: h...

No abnormalities were observed in the mother rats (F0, F1, and F2) and in the offspring (F1, F2, and...

Thus, it was concluded that under the experimental conditions applied, multigenerational whole body exposure to 2.14 GHz W‐CDMA signals for 20 h/day did not cause any adverse effects on the F1, F2, and F3 offspring.
