(ORDO NEWS) — Biologists from the University of Oregon have found out what effect the 3.5 GHz radio waves used in 4G and 5G networks have on the development of zebrafish fish embryos.
Scientists placed the fish eggs in a special container and exposed to it with radio waves for almost two days starting from 6 hours after fertilization. After another three days, the fish larvae were examined for possible morphological and behavioral changes.
As a result, no significant change in the level of mortality, morphology, and reaction to light was detected, but a certain level of sensorimotor disturbance was revealed in the larvae. From which the authors of the study conclude that 3.5 GHz radio waves have a rather mild effect, with the exception of a small effect of suppressing sensorimotor functions.
Nevertheless, scientists do not exclude that the result of exposure to radio waves of a given frequency may be molecular changes or delayed deviations that could not be verified during this study. For example, detected sensorimotor disorders may be an early sign of neuropsychiatric consequences in adulthood.
The authors of the study are sure that in order to get a more detailed picture, further experiments are needed with a longer exposure to radio waves and faster modulation of their frequency – as it happens in real mobile communication networks.
In this connection, they intend to continue studying the effects of radio waves and other radiation, especially since the experimental setup they created provides ample opportunities for this.
