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.

Abstracts National Institute of Environmental Health Sciences Second Biennial Science Seminar

M. J. Ortner et al. · 1979

Researchers exposed isolated rat peritoneal mast cells to 2450 MHz microwave radiation at 8.5 and 42.5 mW/ml for up to 3 hours while maintaining the cells at 37°C. The exposure caused no change in cell morphology or viability as measured by Trypan Blue exclusion. Prior or simultaneous microwave exposure did not alter the cells' secretory response to compound 48/80. Heating cells to 45°C for 10 minutes made them refractory to 48/80, but microwave-exposed cells at 37°C responded normally, indicating no heat-induced membrane damage.

Introduction, Brief Background, and Some Uses of Radiofrequency (RF) Sealers, Heaters, and Gluers

Zory R. Glaser · 1979

RF sealers, heaters, and gluers are also known as heat sealers, fusers, nolders, fasteners, embossers, high frequency sealers or dryers, electronic or electromagnetic sealers or welders, and dielectric heaters. Most devices operate between 3 and 100 MHz, with sealers commonly using ISM bands at 13, 27, and 40 MHz. An estimated 20,000 sealers are in use operated by approximately 30 to 40,000 workers.

Measurements of Electromagnetic Fields in the Close Proximity of CB Antennas

Paul S. Ruggera · 1979

This 1979 government study measured electromagnetic field levels near Citizens Band (CB) radio antennas to understand exposure patterns in close proximity to these transmitters. CB radios operate around 27 MHz and were extremely popular communication devices in the late 1970s. The research provided important baseline data for assessing RF exposure from CB antenna installations.

Government Program on Bioeffects of Nonionizing Radiation -- FY 1978 Project Resume's

H. Janet Healer · 1979

This 1979 government report by H. Janet Healer documented a comprehensive federal program studying the biological effects of nonionizing radiation, including radiofrequency and microwave sources. The report compiled project summaries from various government research initiatives investigating how RF/MW radiation affects living systems. This represents early official recognition that nonionizing radiation warranted systematic health investigation.
