View Original AbstractThis study found brain blood flow changes during phone use, but researchers attributed them to subtle sounds rather than EMF radiation.
Plain English Summary
Researchers used PET brain scans to measure blood flow in 14 people while they were exposed to a 902 MHz mobile phone signal. They found decreased blood flow in the auditory areas of the brain, but not in the areas where EMF exposure was strongest. The researchers concluded this was likely due to subtle sounds from the phone rather than the electromagnetic radiation itself.
Study Details
The aim of this study is to imvestigate Effects of a 902 MHz mobile phone on cerebral blood flow in humans: a PET study.
Fourteen healthy right-handed subjects were scanned using PET with a [15O]water tracer during exposu...
Exposure to an active mobile phone produced a relative decrease in regional cerebral blood flow (rCB...
Therefore, it is not reasoned to attribute this finding to the EMF emitted by the phone. Further study on human rCBF during exposure to EMF of a mobile phone is needed.
