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.

Radio-Frequency and Microwave Radiation

Howard Bassen · 1980

This 1980 FDA research by H. Bassen examined radio-frequency and microwave radiation exposure measurement and safety standards. The study focused on how these electromagnetic fields are absorbed by human tissue and established methods for assessing exposure levels. This represents early foundational work in understanding RF/microwave radiation effects on human health.

HI-3001 Isotropic Broadband Survey Meter

Unknown authors · 1980

The instrument measures fields from 0.5 MHz to 1000 MHz and from 1 v/m to 3160 v/m in six ranges. Its isotropicity is specified as +1 dB over the full rotation of the probe head. The standard battery pack provides approximately 40 hours of continuous operation.

HI-3001 Isotropic Broadband Survey Meter

Unknown authors · 1980

This 1980 technical report documented the HI-3001 isotropic broadband survey meter, a device designed to measure electromagnetic fields across multiple frequencies from all directions simultaneously. The meter represented early efforts to create comprehensive RF measurement tools for assessing environmental electromagnetic exposures. This type of instrumentation became foundational for modern EMF exposure assessment and safety monitoring.

A Study To Investigate Federal Regulation of Microwave Standards

Leonard David · 1980

The study outlines the historical background of U.S. microwave exposure guidelines and identifies the lead federal agencies. No federal standards exist to protect workers or the public, only a voluntary 10 mW/cm² guideline from 1966. Regulatory trends point toward more stringent occupational and public exposure limits, possibly as low as 1 mW/cm². The SPS system would deliver 23 mW/cm² at the rectenna center, 1 mW/cm² or less at the edge, and 0.1 mW/cm² at the buffer zone boundary. Current data show no morbid effects from 2,450-MHz radiation below 1 mW/cm², but long-term exposure studies are lacking.

Measurements of Electromagnetic Fields in the Close Proximity of CB Antennas

Paul S. Ruggera · 1979

This 1979 government report measured electromagnetic field levels near Citizens Band (CB) radio antennas to assess exposure risks. The study documented RF radiation levels that people might encounter when operating or standing close to CB antenna systems. This research provided early data on RF exposure from popular two-way radio equipment used by millions of Americans.
