Guest guest Posted October 2, 2004 Report Share Posted October 2, 2004 The other day I turned on the computer with a pocket radio going and could hear the interference with the radio waves as the computer sprang to life. Lately can feel a kind of buzz from the mouse. I’m beginning to wonder how safe it is to sit in front of the monitor and what kind of circuit I could be forming between the mouse, keyboard, and my body. I did a little research and learned that I need to sit farther from the monitor. Here is one reference I found on the Internet. & #61623; “Stay an arm’s length away from your screen.(30 inches or 75 centimeters) If this makes viewing the monitor more difficult, try increasing text size. “ Any suggestions to avoid problems? Is there protective gear or a special mouse to avoid electromagnetic pollution? http://www.slais.ubc.ca/courses/libr500/02-03-wt1/www/A_Davis/radiation.htm Electromagnetic Radiation What is Electromagnetic Radiation? Many of us spend much of our workday and sometimes even our leisure time in front of a computer monitor. Electromagnetic fields (EMFs) are invisible lines of force that occur whenever electricity is being conducted, whether from a natural source such as the sun, lightning bolts, or atmospheric and solar disturbances, or a man-made source such as electric lighting, microwaves, televisions, or computers. Computer monitors generally emit an extremely low frequency field, called ELF, and they also give off energy in the form of static electric fields and high-pitched sounds (Stigliani 1995,207). Effects of Electromagnetism ELF Magnetic Fields (the low frequency fields emitted from computer monitors) have biological effects that have the potential to do some or all of the following: & #61623; Affect the growth of developing tissue & #61623; Contributing factor of miscarriage or birth defects & #61623; Promote the growth of cancer cells & #61623; Interfere with the cell processes and functions & #61623; Alter neurological functions & #61623; Alter the production of neurohormones & #61623; Affect the function of the pineal gland and its hormone, melatonin & #61623; Influence the dopamine, opiate, and pineal systems, which in turn interact with the immune system (Stigliani 1995, 214). There is no scientific proof that these biological effects will happen to people using a computer in everyday situations, but there is always risk for changes at the cellular level to occur that may eventually result in changes to our health. Computer are just one of the many sources of Electromagnetic fields that we are exposed to everyday and it is possible to reduce your level of exposure by doing the following: Reasonable Precautions You Can Take: & #61623; Becoming psychologically stressed by this issue will more than likely cause you more harm than the radiation, so take action to reduce any stress you may have. & #61623; Use a monitor that conforms to MPRII guidelines, which were established by the Swedish National Board of Testing and ensures electromagnetic fields are present at a much lower level than those emitted by most older monitors. & #61623; Stay an arm’s length away from your screen.(30 inches or 75 centimetres) If this makes viewing the monitor more difficult, try increasing text size. & #61623; Stay four feet or 1.2 metres away from the sides and back of monitors, since fields can be stronger there. And be aware that walls or partitions do not block these fields. & #61623; Turn your monitor off when it is not in use. This reduces EMF exposure and saves electricity. & #61623; Consider special precautions if you are pregnant. Some experts recommend limiting the time you spend in front of a computer if you are pregnant, or trying to conceive.

Guest guest Posted October 3, 2004 Report Share Posted October 3, 2004 All, I changed to a flat monitor, I hope it's better for me. Several years ago I got concerned about TV radiation and children and myself. I found out that you can take a portable radio and turn it to AM , and put the dial on a non-station spot. Then turn on TV, comp. monitor or (power box where electricity comes into your place) {or powerlines...} Check the buzz level way away from the object that you need to check, and walk toward the object. The sound level -buzz on the radio will change to louder as you get to /into the radiation fields. Check above , side to side and behind , and underneath especially for TVs. I found the field from our TV was 6 to 8 ft, in all of those directions. Then you want to place a TV so no one is sleeping directly behind , under(downstairs) or above (upstairs). The power boxes on the side of apartments sometimes are on outside of bedroom walls, move your bed away from that wall!!! If you want to get precise, you can order a magnetic radiation detector for extremly low frequency (power lines) and very low frequency (computors and TVs) from SAFE COMPUTING COMPANY 33 william Street Needham , MA 02194 or call 617 444 7778 or 800 222 3003 they also made a screen to place over comp monitors. Many years have gone by since I did buy their meter....I hope they are still in business...today , who knows? NG ps I still get a buz from the mouse on my 2 year old set-up.----- Original Message ----- " as " <glkbreeze Saturday, October 02, 2004 6:45 PM Re: Computer Monitor Safety > > > The other day I turned on the computer with a pocket > radio going and could hear the interference with the > radio waves as the computer sprang to life.

Guest guest Posted October 3, 2004 Report Share Posted October 3, 2004 Thanks for that Nora - I found a strong magnetic field coming from my keyboard - especially on the right-hand side for some reason ... I am in the habit of resting the keyboard on my lap - close to my prostate ! I also checked out my Sony 28inch widescreen which was nowhere near as bad as my Sony 14inch portable + my remote control for the digital set top box was very loud. I went to view a property recently which is for sale and it had a mobile phone mast right outside the place - right outside 2 of the bedrooms ... it would have been interesting to have had my portable AM radio with me!
