4G phone radiation at 2600 MHz creates strongest electric fields in outer head tissues closest to the device.
Plain English Summary
Summary written for general audiences
Researchers used computer modeling to calculate electric field strength inside a human head exposed to 4G mobile phone radiation at 2600 MHz. The study found that the strongest electric fields occur in the outermost layers of the head, closest to the phone. This modeling work helps scientists understand how deeply cell phone radiation penetrates into brain tissue.

}Quick Questions About This Study
Computer modeling shows 2600 MHz radiation creates the strongest electric fields in the outermost layers of the head, with field strength decreasing as it penetrates deeper into brain tissue.
The skin, skull, and outer brain regions closest to the phone absorb the highest levels of 2600 MHz radiation, while deeper brain tissues experience lower field strengths.
This study specifically modeled 2600 MHz, a frequency used in 4G networks, providing data on how newer cellular technology interacts with head tissues compared to older frequencies.
This model used sixteen different tissue types with realistic electromagnetic properties, creating a highly detailed representation of how 2600 MHz radiation actually behaves in human head tissue.
No, the modeling shows 2600 MHz radiation creates uneven field patterns, with the highest concentrations near the phone and decreasing strength in deeper brain regions.
