EMF in Personal Devices & Wearables

  • -These are the devices that travel with you everywhere-in your pocket, on your wrist, in your ears, and on your lap.
  • -Personal devices and wearables represent your most intimate EMF exposure because they're designed to stay close to your body throughout the day.
  • -Your smartphone radiates radiofrequency energy just inches from your brain during calls, your laptop emits magnetic fields directly onto your lap, and your wireless earbuds transmit Bluetooth signals inside your ear canals.

BIOLOGICAL EFFECTS OF ELECTROMAGNETIC RADIATION – DESIGNATION OF PROJECT OFFICE

Department of the Navy, Bureau of Medicine and Surgery · 1971

The instruction designates a BUMED Project Office for Biological Effects of Electromagnetic Radiation. The project covers the entire electromagnetic spectrum from cosmic rays to extremely low frequency, with primary interest in microwave and extremely low frequency areas. The mission is to provide the Chief of the Bureau of Medicine and Surgery and the Operating Forces of the Navy, and other Services and agencies when requested, with information and research data concerning the biological effects of electromagnetic radiation.

Die morphologischen Veränderungen der Plazenta unter dem Einfluß der Kurzwellendurchflutung. Tierexperimentelle Untersuchungen

Mohammed Moayer · 1971

This 1971 study examined how short-wave radiofrequency radiation affects the structure and appearance of placental tissue in laboratory animals. The research focused on identifying physical changes to the placenta following RF exposure during pregnancy. While specific findings aren't available, this represents early research into how electromagnetic fields might impact developing pregnancies.

VHF-UHF RADIATION HAZARDS AND SAFETY GUIDELINES

J. Damelin · 1971

The report explains that high-power VHF-UHF radiation can harm people and animals by overheating tissue. It defines radiation protection guide numbers of 10 and 1.0 milliwatts per square meter for different temperature-humidity indices. If the curves indicate a potential hazard, the actual antenna system must be analyzed with extensive near-field calculations.

BIOLOGICAL EFFECTS OF MICROWAVE RADIATION, PART 1

Heering, van Osch · 1971

The report defines microwave radiation as electromagnetic radiation covering the range between conventional radio waves and far infrared. It explains that microwave absorption in tissues depends on water content and frequency, with fat allowing deeper penetration than muscle. The report classifies biological effects into thermal, specific thermal, and non-thermal categories and notes that harmful thermal effects usually occur at power densities exceeding 100 aW/on.

Danger of Overwarming Blood by Microwave

Arens JF, Leonard GL · 1971

This 1971 study examined the dangers of using microwave energy to warm blood for medical transfusions, focusing on risks of hemolysis (blood cell destruction) and overheating. The research investigated how microwave heating could overwhelm or damage blood components, making it unsafe for patient use.
