The launch of super-fast 5G technology over the next several years will dramatically increase the number of transmitters sending signals to cellphones and a host of new Internet-enabled devices, including smart appliances and autonomous vehicles. And the move to the new technology comes after unsettling findings from a long-awaited federal government study of the cancer risk from cellphone use.
National Toxicology Program researchers released preliminary data in May that showed small increases in tumors in male rats exposed to cellphone radiation.
The rats were exposed to nine hours of radiation daily, in 10-minutes-on, 10-minutes-off intervals, over their whole bodies for two years. The researchers found increased incidences of rare brain and heart tumors starting at about the federally allowable level of cellphone radiation for brain exposure, with greater incidences at about two and four times those levels.
