Just scratching beneath the surface I found:

• a vast collection of related materials from Environmental Health Trust ... some of questionable quality.
• lots, and lots of photoshopped stock photography (not science)
• various pseudoscientific mambo-jumbo snake oil salesmen e.g.: VERACASS "Wellness Technology".
• and one scientific paper "EEG Changes Due to Experimentally Induced 3G Mobile Phone Radiation" (Roggeveen et al., 2015)

Make of it what you will.
