View Original AbstractCell phones deliver only microscopic amounts of RF energy to the pineal gland, making thermal damage to this sleep-regulating brain structure highly unlikely.
Plain English Summary
Researchers measured how much radiofrequency energy from cell phones actually reaches the pineal gland, a small brain structure that produces melatonin and regulates sleep cycles. Using tissue samples from 20 human pineal glands and computer modeling, they found that even when a phone operates at maximum power next to your ear, only tiny amounts of RF energy (11 microwatts) are absorbed by this deep brain structure. The scientists concluded that cell phone radiation is unlikely to cause temperature-related effects in the pineal gland.
Study Details
In order to enable a detailed analysis of radio frequency (RF) absorption in the human pineal gland, the dielectric properties of a sample of 20 freshly removed pineal glands were measured less than 20 h after death.
Furthermore, a corresponding high resolution numerical model of the brain region surrounding the pin...

These results indicate that temperature-related biologically relevant effects on the pineal gland induced by the RF emissions of typical handheld mobile communication devices are unlikely.
