Abstract

"This paper addresses the argument stating that since the energy of a single RadioFrequency (RF) photon is extremely small it cannot influence matter significantly and therefore RF radiation cannot cause cancer. The argument is shown to be wrong sincemost known phenomena and uses of RF radiation involve many photons acting in unison.For example in a particle accelerator a multitude of RF photons act simultaneously on asingle elementary charged particle. We show that his holds for particle physics, capacitors,fluorescent tubes, radio communications, RADAR and living tissues. These phenomena arebest treated by considering RF radiation as a wave phenomenon."

In other words this scientific paper shows that all forms of Radio Frequency radiation - including microwaves from mobile or wireless devices - CAN cause Cancer.
