“Absorption of 5G Radiation in Brain Tissue as a Function of Frequency, Power and Time,” IEEE Access, June 12 2020, updated July 2, 2020.

”We examine the beam penetration, absorption and thermal diffusion at representative 4G and 5G frequencies and show that the RF heating increases rapidly with frequency due to decreasing RF source wavelength and increasing power density with the same incident power and exposure time.”
