What this modeling shows is that the situation is not good now, and it’s going to get much worse under 5G regimes.

Abstract

Radio-frequency electromagnetic fields (RF-EMFs) can be absorbed in all living organisms, including Western Honey Bees (Apis Mellifera). This is an ecologically and economically important global insect species that is continuously exposed to environmental RF-EMFs. This exposure is studied numerically and experimentally in this manuscript. To this aim, numerical simulations using honey bee models, obtained using micro-CT scanning, were implemented to determine RF absorbed power as a function of frequency in the 0.6 to 120 GHz range. Five different models of honey bees were obtained and simulated: two workers, a drone, a larva, and a queen. The simulations were combined with in-situ measurements of environmental RF-EMF exposure near beehives in Belgium in order to estimate realistic exposure and absorbed power values for honey bees. Our analysis shows that a relatively small shift of 10% of environmental incident power density from frequencies below 3 GHz to higher frequencies will lead to a relative increase in absorbed power of a factor higher than 3.

From Discussions

The results of our numerical simulations, see Fig. 5, show an increase of Pabs with frequency up to 6–12GHz. Figure 4 illustrates the mechanism behind this increase: as the frequency increases the EMFs are less likely to diffract around the honey bees, that are relatively small in comparison to the wavelengths <6GHz, and can penetrate further in the models, generating higher internal electric fields and consequently higher Pabs values.

…The results in terms of Pabs obtained for the honey bees in this study fall right in between those obtained in 11 for the smaller Australian Stingless Bee and the larger Desert Locust, which confirms again the dependency of Pabs on phantom size. The same size-related effect was described for humans in 28,33,38 and comparable frequency trends were observed in humans that have larger full-body sizes at MHz frequencies 28,38. It should be noted that this manuscript focused on exposure of individual insects in free space. In reality, honey bees might cluster, creating a larger absorption cross section and potentially higher absorption at lower frequencies.

…As our RF-EMF exposure measurements near bee hives demonstrate, see Table 2, most of the current RF-EMF exposure is located at frequencies ≤1GHz. Additionally, Fig. 5 demonstrates that the Pabs in all studied Honey bee models is lowest at frequencies ≤1GHz. This implies that in reality, potential shifts in telecommunication frequencies to higher frequencies might induce even larger increases that the ones estimated in Table 4 since in that analysis an average value over all Pabs values ≤3GHz is assumed.

From Conclusions

Assuming that 10% of the incident power density would shift to frequencies higher than 3GHz would lead to an increase of this absorption between 390–570%. Such a shift in frequencies is expected in future networks.
