2020- 07-13 IEEE reports milliwaves cause heating

1) Another article published by IEEE, one that is rather technical. I don’t understand much of it but there are many significant points that we need to be aware of. I found a few and have copied them below. I have asked technical people to provide comments on things I might have missed or to offer insights. This article clearly shows that there are heating effects noted after even short periods of exposure to higher frequencies that already are being used by 5G. The beam forming is especially responsible for biological reactions. Of course there is no mentions of other biological harm and this is not surprising since IEEE, like ICNIRP, recognizes harm from thermal radiation only. If it does cook you, it doesn’t hurt you could be their motto.

My fear is that this information will be ignored, that devices will continue to be sold, installed, and allowed even though this industry group acknowledges potential harm.

Absorption of 5G Radiation in Brain Tissue as a Function of Frequency, Power and Time

“This also means that the surface temperature increases rapidly with higher frequency in the 5G bands and with the onset of heat diffusion has less dependence on exposure time.

Therefore, the use of gel (or liquid) substances leads to a gross underestimation of the thermal gradients, and yields a temperature rise that is much smaller than that observed in the actual tissue. Differences observed between the brain tissue and gel, especially at the higher power levels and higher 5G frequencies, indicate that care must be taken when extrapolating tissue data from such measurements in addition to any differences in dielectric properties. A nonlinear relation between the temperature and power density indicates severe heating with subsequent tissue or gel damage, and the onset of thermal convection (gel state change).”

“The impinging RF radiation causes complex simultaneous dynamic effects inside the brain tissue as a result of beam penetration, absorption and thermal diffusion, that need to be taken into account to assess the impact of exposure accurately as a function of frequency, power and time. Although, the overall temperature rise is nonlinear with time, it is linear over short intervals, as is the absorbed RF power at discrete exposure times and depths inside the tissue at each frequency we measured.”

Compared to the lower frequency, at 39 GHz the RF heating is higher at every depth while RF absorption is very confined to the surface of the sample (see Appendix) and the resultant rapid changes in the heating and cooling curves are very apparent in both the brain and gel.”

“Although, RF energy density increases near the surface with higher frequency, the heating rate still increases significantly at depth as a result of heat diffusion.”

The SAR is measurable below 6 GHz by the field probe method but not above 6 GHz due to the decreased beam penetration and increased power absorption near the surface of the tissue requiring the measurement of epithelial (absorbed) power density.”

“It should be noted that the frequency (and wavelength), waveguide aperture area or dipole antenna length, and average power density are all interrelated. Increasing frequency, decreases the appropriate waveguide area or the resonant antenna length and increases the average incident power density drastically for any prescribed power.”

“We also note that the impact of relatively modest incident RF power (1 W) and short exposure times (6 minutes CW and 30 second pulsed) at 39 GHz using a single mode waveguide source for the exposure, results in extremely large power density (16.5 kW/m2) and temperature rise (=60°C for CW, =35°C for 30 s pulse) in both bovine brain tissue and gel. This same temperature rise can be expected on skin (which has very similar dielectric properties) when such large surface power densities are present in very close proximity to the RF source or antenna, perhaps emanating from millimeter-wave base stations, handsets, or wireless-enabled appliances or kiosks.”


2) In New York City, 5G is going live using a variety of frequencies, from 600 MHz to 28 GHz.

5G “Layer Cake” Activated in New York City by T-Mobile in May

“T-Mobile today turned on its newly integrated 2.5 GHz spectrum in New York City, making it the first city to offer the operator’s full “layer cake” for 5G with a mix of low-, mid-, and high-band spectrum….

In addition to the 2.5 GHz, making up T-Mobile’s 5G layer cake in NYC is low-band 600 MHz and millimeter wave 28 GHz spectrum. AT&T, meanwhile, has its low-band and mmWave “5G+” service live in New York and competitor Verizon launched mmWave 5G using 28 GHz in the city in September 2019.”
