Why is Radiation From Cellphones Bad?
Another concern with the use of cell phones is brain damage from radiation. For years, scientists have been concerned that the radiation given off by cellphones could possibly harm us in the long run. On one hand, some argue that radiation has no effect on the brain, not even changing the formation of tumor cells that are already formed on some brains. In the article Exposure to 3G mobile phone signals does not affect the biological features of brain tumor cells, published in 2015, in the Bio Med Central Journal, authors Yu-xiao Liul, Guo-qing Li, Xiang-ping Fu1, et al., are investigating whether or not mobile phones could make changes in human tumor cells, acting as a tumor promoting agent. The authors start out the article by stating that with the increase in cell phone use there has been an uprising concern about the development of brain tumors in the users. As the article continues into more detail, steps are made to test the effects on the brain from 1950-MHz (which is radiofrequency electromagnetic fields) TD-SCDMA exposure. The authors had three specific things that they were testing. The first was how 1950-MHz TD-SCDMA exposure affected the biological features of glioblastoma cells in vitro. The authors’ second test is how that type of exposure affects gene expression and profiles. Lastly the authors tested to see if EMF changed the formation of a tumor cell. They observed the cells for long periods of time and documented the results from the tests. The authors finish the article by explaining that all of the exposure to the brain tumors made no changes to the cells and had no effect on the brain in the 48 hours that it was being tested. On the other hand, however, others argue that holding the cell phone to the ear to talk rather than talking on speaker phone or texting, can cause radiation to stream right into the brain, leading to cancerous tumors.
