I've had a similar experience to this before. Back in the early days of computers, before Al Gore and I invented the internet, you communicated with a computer through a video display terminal. It was basically a teletype combined with a TV monitor. The highest frequency in one of these was the horizontal deflection frequency of 15 thousand hertz. The definition of microwaves is a frequency higher than 1000 mega hertz. OK so the VDT has 15000 and microwaves begin at 1 thousand million. I read this long rant in Byte magazine about the dangers of microwave radiation from VDTs. B S.

High >> frequency ionizing forms of radiation exists as X-rays, Gamma rays and >> forms of nuclear radiation known to be hazardous . Non-ionizing >> radiation of lower >> frequency ionizing forms such as early cell phones were thought to be >> safe. That view has changed since cell phones and mobile phones have >> grown in strength >> from low-level radio waves to high-level microwaves.

Perhaps this is why governments and health organizations >> worldwide are spending >> millions of dollars towards on-going research to determine the long term >> effects of exposure to E.M.R from cellular and mobile phones. >> >> What is S.A.R.? >> Answer: S.A.R. or Specific Absorption Rate of Radiation is used to >> measure the amount of radiation that the human body absorbs from any >> source, including >> cellular phones. The F.C.C. (Federal Communications Commission) sets >> limits as to what they deemed were safe levels of radiation from cell >> phones. In the >> beginning when analog phones were 800-900 MHZ of power, most of the cell >> phones manufactured met these safe guidelines. However as manufacturers >> raised >> the power of their phones up to 1800-2000MHZ and analog was replaced by >> digital, the majority of the cell phones now exceed the safe levels set >> by the >> F.C.C. In fact the manufacturers continue to lobby to have the levels >> raised, so they may keep increasing the power of the phones. The highest >> S. A. R. >> in the body is in the ear, thus the concern about excessive cell phone >> use and the strength of the signal. >> >> How is S.A.R. measured on a cell phone? >> Answer: When a call is made or received there is a band of radiation >> from the antenna, half of which disappears into space. The remaining >> radiation is around >> the skull, face and ear area of the user and runs through the circuitry >> of the phone when transmitting the call. A dummy head is immersed in a >> gel-like >> solution similar to body fluid and a cell phone is attached to the ear. >> Readings are taken from the antenna to determine the S.A.R. strength >> which will >> vary from phone to phone and proximity to the closest signal tower. >> >> What is the difference between a Radio Wave and a Microwave? >> Answer: Radio Waves are low levels of transmission power for signals to >> and from your phone. These non-ionizing frequencies of radiation are >> safe. However >> as signal strength grows from a few hundred MHZ of power to beyond 800 >> MHZ, the electromagnetic spectrum increases and these waves become >> microwaves. For >> example, the older mobile house and office phones were a few hundred MHZ >> of radio waves but the farther you moved from the base, the weaker the >> signal >> became and you would lose the call or it would break up. Now mobile >> phones are 900MHZ to 2.4GIGS or more of power so you do not lose the >> calls as you travel >> from room to room or go outside, but your phone is now into >> Microwaves/infrared waves of radiating power. >> >> Question: Is it true that radiation comes from the aerial? >> Answer: Yes, as we explained in the S.A.R. question, there is a band of >> radiation around your head from the antenna half of which disappears >> into space. >> However the skull is hard and there are calcium deposits for some >> protection. The most vulnerable area for radiation is the soft tissue of >> the inner ear >> where most of the reports of tumors have been reported. And as we stated >> the highest incidence of S.A.R. in the body is in the ear. We have found >> no reports >> of tumors on the skull, chin, face or opposite side of the head, but >> mainly behind the ear where the phone is placed when receiving or >> transmitting a call. >> >> Question: What is meant by the term NEAR-FIELD RADIATION? >> Answer: Near-field refers to that portion of the radiation coming off >> the antenna that goes directly into the inner ear when you place the >> phone against >> your ear to make or receive a call. This portion of the radiation is >> considered the most dangerous to the user for two reasons: 1) As stated, >> the highest >> incidence of radiation in the body is in the ear and 2) most of the >> reports of tumors have been reported just behind the ear, thus any >> product that could >> effectively block that portion of radiation from entering the inner ear >> would be a valuable health tool. >> >> Is there any proof that cell phones are dangerous? >> Answer: The jury is still out on the long term effects of cell phone >> use, while in the meantime governments worldwide and health >> organizations like the >> World Health Organization continue to allocate millions of dollars >> towards on going research to determine the effects of cell phone usage. >> These organizations >> along with others are documenting more reports of brain tumors and >> increased cases of litigation against cell phone manufacturers. >> Question: Are there >> any danger signals from excessive cell phone use? Answer: Many users >> report symptoms like hot phones, headaches, fatigue, tingling sensations >> and even >> memory loss. Of course some phones are hotter than others. In a study of >> teens under 16 years of age, scientists in Europe reported short-term >> memory loss >> (up to 50 minutes) after using a cell phone. >> >> Should I be concerned about my teenager using a cell phone? >> Answer: By all reports, you should be concerned especially for the >> younger adolescent child. Their brain tissues are still growing, their >> skull is half >> as thick as adults yet we see a growing use of cell phones worldwide by >> young teens. >> >> What about using a hands-free kit to keep the phone away from my head? >> Answer: Hands-free kits are currently used for convenience, by law in >> some states while driving a vehicle and mostly by concerned cell phone >> users who want >> to keep the phone away from their head because of concern about >> radiation. However in studies and tests of many of the hands-free kits >> by scientists and >> consumer groups in Europe, they found that the wire from the ear piece >> acts as an aerial and actually increases the radiation by three times. >> >> Are there any steps I can take to reduce the potential risk of cellular >> radiation? >> Answer: Yes, first use a phone with a long ariel pointed away from the >> head. Every inch is important. Unfortunately we see manufacturers making >> phones with >> short stub antennas or the antenna inside the phone because the phone >> has more design style. If you must use a phone in the car, use a speaker >> phone so >> there is no contact between you and the phone. Cut out non-essential >> calls to reduce time spent on the phone. In particular replacing your >> existing mobile >> phones at home with cellular free long distance plans is not a good >> idea. You may save money but in the long run not save your health.

Look or >> ask for >> valid testing of the product used on actual phones by a recognized >> testing authority.
