Rats exposed to 915 MHz RFID for 2 or 16 weeks showed unchanged relative cerebral glucose metabolic rate in the frontal, temporal, and parietal cortexes.

Plain English Summary

Summary written for general audiences

Male Sprague-Dawley rats were divided into cage-control, sham-exposed, and RFID-exposed groups and exposed to 915 MHz RFID for 8 h daily, 5 days per week, for 2 or 16 weeks. The whole-body average specific absorption rate was 4 W/kg. FDG-PET images were obtained the day after RFID exposure using micro-PET with a FDG tracer, and the relative cerebral glucose metabolic rate was unchanged in the frontal, temporal and parietal cortexes of exposed rats compared with cage-control and sham-exposed groups.

Why This Matters

The study aimed to investigate the effect of whole-body 915 MHz RFID exposure on rat cortical glucose metabolism using FDG-PET. Researchers measured absolute glucose metabolism values in regions of interest in the frontal, temporal and parietal cortexes and cerebellum, then normalized cortical values to the cerebellum.

Study Details

We investigated the effect of whole-body exposure to 915-MHz radiofrequency identification (RFID) on rat cortical glucose metabolism by using (18)F-deoxyglucose positron emission tomography (FDG-PET).

Our results suggest that 915 MHz RFID radiation exposure did not cause a significant long lasting effect on glucose metabolism in the rat brain.
