View Original AbstractFour weeks of cell phone-level RF exposure showed no effects on brain blood vessels in rats.
Plain English Summary
Researchers exposed rats' heads to cell phone-level radiation (1439 MHz) for one hour daily over four weeks to study effects on brain blood vessels. They found no changes in blood-brain barrier function, immune cell behavior, or blood flow in the brain. This suggests that this level of radiofrequency exposure may not disrupt the brain's delicate blood vessel system.
Study Details
The aim of this study was to investigate whether repeated exposure to radio frequency electromagnetic field (RF-EMF) of 1439 MHz affects the cerebral microcirculation, including blood-brain barrier function, in a rat brain.
The head of the rat was exposed for four weeks (60 min/day, 5 days/week) to RF-EMF at 2.4 W/kg of br...
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.
