The study found no albumin leakage and no increase in dark neurons in rat brains after 915 MHz exposure.

Plain English Summary

Summary written for general audiences

Researchers exposed sixty-four male F344 rats to a 915 MHz electromagnetic field at whole-body average specific absorption rates of 0, 0.02, 0.2 and 2.0 W/kg for 2 hours. The brains were examined 14 and 50 days after exposure using histological and immunohistochemical methods. No albumin immunoreactivity was observed in any exposed group. Dark neurons were rare and did not differ significantly between exposed and sham-exposed animals. The authors concluded that the study did not confirm the earlier findings of Salford et al.
