“RF-Induced Temperature Increase in a Stratified Model of the Skin for Plane-Wave Exposure at 6-100 GHz,” Radiation Protection Dosimetry, posted January 16, 2020.

“The maximum observed temperature increase is 0.4°C for exposure at the present power density limit for the general population of 10 W/m² [1 mW/cm²]. This result is more than twice as high as the findings reported in a previous study.” From IT’IS in Zurich.

“Systematic Derivation of Safety Limits for Time-Varying 5G RF Exposure Based on Analytical Models and Thermal Dose,” Health Physics, December 2018.

“Another conclusion of this study is that the current ICNIRP (1998) and IEEE (2005, 2010) guidelines urgently need to be revised, as the duty cycle of 1,000 currently tolerated can produce unacceptable temperature increases that may result in permanent tissue damage.” From IT’IS in Zurich.

Are All Effects Thermal?

"Are there any biological effects that are not caused by an increase in tissue temperature (nonthermal effects)?" That was one of the "overarching issues" considered by the NAS-NRC committee at the workshop it hosted last August (see p.11 of the its final report, as well as our August 10, 2007 and January 17, 2008 posts). At the time, France's Bernard Veyret, the member of the committee who led the discussion, expressed skepticism that such effects had been reliably documented.
