This exposure assessment study evaluated 5G RF-EMF exposure using both theoretical extrapolations and direct measurements in semiurban and urban settings, including a campus case study. Measured and extrapolated exposure levels were reported to be within ICNIRP recommended limits, even under high network data demand. The authors also report a strong correlation between theoretical and instantaneous field exposures, supporting the validity of their dual-method framework.
Exposure to 900 MHz electromagnetic fields activates the mkp-1/ERK pathway and causes blood-brain barrier damage and cognitive impairment in rats
This animal study exposed 108 male Sprague-Dawley rats to 900 MHz EMF (1 mW/cm2) or sham for 14 or 28 days (3 h/day). The authors report that 28-day exposure was associated with impaired spatial memory, BBB permeability damage, and ultrastructural changes in hippocampus and cortex. They also report increased mkp-1 expression and ERK dephosphorylation, proposing activation of the mkp-1/ERK pathway as a mechanism.
