View Original AbstractFive-minute cell phone exposures showed no immediate changes in brain blood flow, but longer-term effects remain unstudied.
Plain English Summary
Finnish researchers used advanced brain imaging (PET scans) to measure blood flow in the brains of 15 men while they were exposed to cell phone radiation for 5 minutes from different positions around their heads. The study found no changes in brain blood flow despite the radiation causing a slight temperature increase in the ear canals, suggesting that short-term cell phone exposure doesn't immediately affect how blood circulates in the brain.
Study Details
The present study investigated the effects of 902.4 MHz global system for mobile communications (GSM) mobile phone radiation on cerebral blood flow using positron emission tomography (PET) with the (15) O-water tracer.
Fifteen young, healthy, right-handed male subjects were exposed to phone radiation from three differ...
The exposure induced a slight temperature rise in the ear canals but did not affect brain hemodynami...
The results provided no evidence for acute effects of short-term mobile phone radiation on cerebral blood flow.
