Adolescent rats exposed to mobile phone RF-EMR showed signs of increased emotionality without changes in general locomotion.

Plain English Summary

Summary written for general audiences

Researchers exposed male adolescent rats to radio-frequency electromagnetic radiation at 900 MHz from an active mobile phone, then tested their emotionality and locomotion. In the elevated plus maze test, exposed rats showed significantly reduced open-arm entries, time on open arms, and distance on open arms, along with decreased rearing and grooming frequency. Total distance travelled and total arm entries did not differ significantly between exposed and control rats.

Why This Matters

Male albino Wistar rats that were 6 to 8 weeks old were randomly assigned into groups having 12 animals in each group. The sham-exposed group was exposed to a mobile phone in switch-off mode, while the RF-EMR group was exposed to an active GSM mobile phone with a peak power density of 146.60 μW/cm2 for 28 days. Defecation boli count during the elevated plus maze test was higher in the RF-EMR group. The researchers concluded that mobile phone radiation could affect the emotionality of rats without affecting general locomotion.
