What problems was revealed in early electromagnetic experiment?

 

Electromagnetic experiment was started since the 60s.

 

In the 1960s

Freelance biophysicist and engineering psychologist Alan Frey was the first to discover that people and animals can hear low-energy pulsed microwaves.

Frey found that when microwaves of 300-3,000 megahertz were pulsed at specific rates, humans (even deaf people) could "hear" them.

The beam caused a booming, hissing, clicking or buzzing sound, depending on the exact frequency and pulse rate.

And the sound seemed to come from just behind the head.

Later electromagnetic experiment showed that microwaves are sensed somewhere in the temporal region just above and slightly in front of ears.

This is caused by pressure waves set up in brain tissue. Some waves activate sound receptors of inner ear via bone conduction, while others directly stimulate nerve cells in auditory pathways.

Electromagnetic experiments on rats showed that a strong signal can generate sound pressure of 120 decibels, or approximately the level near a jet engine at take-off.

Frey also knew that microwaves could slow down, speed up or even stop the heartbeat. In other words, it is technically possible to cause a heart attack by directing a microwave beam to human body. It can also create leaks in the blood-brain barrier.

 

In the 1970s

Dr Joseph C. Sharp who served as an army test subject in an electromagnetic experiment, confirmed Frey's finding. Sharp heard and understood spoken words delivered to him in an echo-free isolation chamber via a pulsed-microwave audiogram (an analog of the words' sound vibrations) beamed into his brain.

This device was useful in army covert operations designed to drive a target crazy with " voices" or deliver undetectable instructions to a programmed assassin.

 

In the 1980s

Eldon Byrd who developed electromagnetic devices for US Navy, later wrote of alterations in brain function of animals exposed to low intensity electromagnetic fields.

He found that offspring of exposed animals "exhibited a drastic degradation of intelligence later in life... couldn't learn easy tasks...indicating a very definite and irreversible damage to central nervous system of fetus."

He also wrote of electromagnetic experiment where animals' behavior was controlled by weak electromagnetic fields exposure. "At certain frequency and power intensity, they could make the animal purr, lie down and roll over."

 

In the 1990s

An electromagnetic research by Dr Samuel Milham, found that workers in 10 occupations had higher electromagnetic field exposures than non-electrical workers. These occupations are:

  • electrical engineering technicians
  • electrical engineers
  • electricians
  • cable workers
  • power line workers
  • power station operators
  • telephone line workers
  • TV and radio repairmen
  • welders
  • and flame cutters

He also found higher levels of leukemia and lymphoma among workers in aluminum smelters, which use very large amounts of electrical power.

An initial US Environmental Protection Agency report in 1990 even recommended that electromagnetic field be considered a class B carcinogen, a class that included known cancer-causing agents, like formaldehyde, DDT, dioxins, and PCBs.

Subsequent electromagnetic experiment remained vague.

 

In 2000

Most EMF-related experiments reached vague conclusions, with some even documenting positive effects of electromagnetic field on people!

Stewart Committee is an independent expert group on mobile phones initiated by the UK government and set up in March 1999. On 11 May 2000, they urged a precautionary approach to using mobile phones until there was better scientific evidence. They advised in particular that mobile phones widespread use by children should be discouraged.

 

In 2001

Electromagnetic experiment reveals more positive results of electromagnetic field exposure. However, a study found increased risk of uveal melanoma (a rare tumor of the eye) in people exposed to radio frequency transmitting devices, such as radio sets and mobile phones (Epidemiology).
