Adult female rats exposed to 900 MHz EMF for 28 days had significantly fewer Purkinje cells in the cerebellum than unexposed controls.

Plain English Summary

Summary written for general audiences

Researchers exposed 16-week-old adult female rats to 900 MHz EMF for 1 hour per day for 28 days and then counted Purkinje cells in the cerebellum using a stereological technique. The total number of Purkinje cells in the exposed group was significantly lower than in both the control group (p < 0.004) and the sham-exposed group (p < 0.002). Body and brain weights did not differ significantly between the exposed and unexposed groups.

Why This Matters

The study used three groups: a control group not placed in the exposure tube, a sham group placed in the tube but not exposed to EMF, and an EMF-exposed group. The specific energy absorption rate varied between 0.016 W/kg for the whole body and 2 W/kg locally in the head. The researchers suggested that long-duration exposure to 900 MHz EMF leads to decreases in Purkinje cell numbers in the female rat cerebellum.
