Activists and scientists around the world reports that the NTP (NIH) has halted all studies of RF health & biological damage and harm. This is done 5 years after the NTP Study found that RF radiation caused cancer in rates.
I assume that this is a political decision as the industry does not want the truth to be known and proven.
