View Original AbstractTen-minute exposures to cell phone radiation showed no immediate effects on brain blood circulation in rats, but this doesn't address long-term exposure risks.
Plain English Summary
Researchers exposed rats to cell phone frequency radiation (1,439 MHz) for 10 minutes at three different power levels to see if it affected blood flow and the blood-brain barrier in their brains. They found no changes in any of the brain circulation measurements, including blood vessel size, blood flow speed, and whether the protective blood-brain barrier became more permeable. This suggests that short-term exposure to this type of radiofrequency radiation did not disrupt normal brain blood circulation.
Study Details
THE AIM of this study was to determine the potential of radio-frequency electromagnetic fields (RF-EMF) to affect cerebral microcirculation, including blood-brain barrier function, in rat brain.
The head of the rat was exposed for 10 min to 1439 MHz RF-EMF having three intensity doses: 0.6, 2.4...
No extravasation of intravenously injected dyes from pial venules was found at any BASAR level. No s...
These findings suggest that there were no effects on the cerebral microcirculation under the given RF-EMF exposure conditions.
