On July 9th a new study published in PLOS ONE by Oregon State University showed that 5G (fifth-generation mobile communication technology) does not bring as much radiation as people think. In 2019, 5G technology will be deployed globally, and while it will bring higher network connectivity and download speeds than 4G, many believe it will also have greater radiation to the human body.
“Based on our research, we don’t think 5G radiation is going to be harmful,” said Subham Dasgupta, a postdoctoral fellow at Oregon State University. “
The researchers conducted the study using zebrafish embryos, which have an 87 percent genetic and human similarity, and are an important model animal for life science, health science, and environmental science research, known as the “water rat.” This means that zebrafish research can be easily reflected on humans.
In the study, the researchers exposed zebrafish embryos to 3.5GHz in radio frequency (the frequency normally used by 5G phones) for two days and conducted a series of tests.
As a result, they did not find that radiation had a significant effect on embryo mortality, embryo formation, and the embryo’s behavior response to light. But a small change in sound was found in a test that would react to sudden sounds, and further investigation of the cause was needed.
In the future, researchers say, 5G radiation will be studied on zebrafish from genetic levels and from embryo to adulthood. In addition, the impact of higher frequencies and exposure levels on zebrafish will be studied to keep pace with the changing mobile phone industry.
