5G wireless networks have little impact on health, study using zebrafish model finds – sciencedaily


The results of an Oregon State University study on the effects of radiofrequency radiation generated by wireless technology that will soon be standard for cellphones suggest little impact on health.

Fifth generation or 5G wireless technology, which began rolling out around the world in 2019, offers faster connectivity and more bandwidth, which means higher download speeds.

But because 5G technology is so new, little is known about the potential health effects of its radio frequency radiation, which is above the current industry standard 4G. The Oregon State Study is starting to change that.

“Based on our study, we don’t think 5G radiation is that harmful,” said Subham Dasgupta, postdoctoral fellow working in Robyn Tanguay’s lab in the state of Oregon. “It’s mostly benign.”

The researchers conducted the research using an embryonic zebrafish, a model organism often used to discover interactions between environmental stressors and biological systems. Zebrafish and humans have similar developmental processes and are genomically similar, meaning that zebrafish research can easily be applied to humans.

In the study, published July 9 in the journal PLOS ONE, the researchers exposed embryonic zebrafish for two days to 3.5 GHz radio frequency radiation, the frequency typically used by 5G-enabled cell phones.

They found no significant impact on mortality, embryo formation or the behavioral response of embryos to light. They found a modest impact on a test that measures the response of embryos to a sudden sound which they will study further.

Future research will examine the effects of 5G radiation on the same zebrafish used in the study at the gene level and as they develop from embryos to adults, Dasgupta said. Researchers would also like to study the impacts of higher frequencies and higher exposure levels on zebrafish to keep pace with the changing cell phone industry.

Future research will use the same standardized experimental set-up used in this study. This is a copper box. Zebrafish embryos are placed on plates, which are placed inside the box. The radiation enters the box through an antenna and the copper keeps it inside the box.

It was developed in collaboration with Huaping Liu, a professor at the Oregon State College of Engineering, and several members of his lab.

The other study authors were Guangxin Wang, Michael Simonich, Tingwei Zhang, and Lisa Truong. Tanguay and Dasgupta are in the Department of Environmental and Molecular Toxicology at the Oregon State College of Agricultural Sciences.
