EMF in School / Classroom

  • -## School and Classroom EMF Sources Modern classrooms have transformed into technology-rich environments where students and teachers spend 6-8 hours daily surrounded by multiple EMF-emitting devices.
  • -Today's educational settings typically feature WiFi networks broadcasting throughout the building, individual laptops or Chromebooks for each student, interactive whiteboards at the front of the room, and various Bluetooth-enabled devices for presentations and connectivity.
  • -What makes the school environment unique from an EMF perspective is the density of devices operating simultaneously in relatively small spaces, combined with the extended duration of exposure for both students and educators.

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.

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.
