About Cell Phones EMF

  • -Your cell phone is likely the most significant source of EMF exposure in your daily life.
  • -Every time you make a call, send a text, or stream a video, your phone emits radiofrequency (RF) radiation in the 700 MHz to 2.7 GHz range to communicate with cell towers.
  • -This radiation doesn't stop at your phone's case-it penetrates into your body, with the strongest exposure occurring in tissues closest to the device.

BIOTELEMETRY ANTENNAS IN BIOMECHANICS: THE PROBLEM OF SMALL BODY-MOUNTED ANTENNAS

NEUKOMM Peter A. · 1977

Maximum transmission loss increased from 20 to 30 dB as frequency rose from 200 to 1000 MHz at a 35 mm distance, and from 17 to 24 dB at a 77 mm distance over the same frequency range. The study concluded that ideal telemetry frequencies lie within 75-150 MHz, where losses stay below 18 dB at 35 mm and below 14 dB at 77 mm antenna-trunk distance. The flat helical dipole was recommended as the best antenna for biomechanics telemetry because varying body distance does not detune it out of its bandwidth.

A Current Literature Report on the Carcinogenic Properties of Ionizing and Non-Ionizing Radiation

Unknown authors · 1977

This 1977 technical report reviewed the existing scientific literature on cancer-causing properties of both ionizing radiation (like X-rays) and non-ionizing radiation (including microwaves and radiofrequency fields). The analysis examined various forms of electromagnetic radiation to understand their potential role in cancer development. This represents one of the earliest comprehensive reviews connecting non-ionizing EMF sources to carcinogenic concerns.
