Although there are many uses and advantages for RF technology, there are also health concerns for both humans and the environment. Radiation exposure has long been a concern for the public, policy makers, and health researchers. Beginning with radar used during World War II, human exposure to radio-frequency radiation (RFR) technologies has grown substantially over time.
— Scientific evidence shows that exposure to RF technology, such as cell phones and routers can significantly elevate the risks of brain tumors, glioma and acoustic neuroma, as well as chromosomal DNA damage.
