Fifth generation or 5G wireless technology, which began being deployed worldwide in 2019, provides faster connectivity and more bandwidth, meaning higher download speeds.
But because 5G technology is so new, little is known about the potential health effects from its radiofrequency radiation, which is higher than the current industry standard 4G. The Oregon State study begins to change that.
“Based on our study, we don’t think 5G radiation is that harmful,” said Subham Dasgupta, a postdoctoral fellow working in the lab of Robyn Tanguay at Oregon State. “It’s predominately benign.”
Researchers conducted the research using 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 similar on a genomic level, meaning 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 radiofrequency radiation, the frequency typically used by 5G-enabled cell phones.
They found no significant impacts on mortality, how the embryos formed or the embryos’ behavioral response to light. They did find a modest impact on a test that measures the embryos’ response to a sudden sound that they will investigate further.
