How harmful is too much exposure to "Electric Wave"?

Depends on what sort of electromagnetic waves you mean...\n\nMicrowaves, X-rays etc\n\nStudies are being conducted all the time to test this, but most electromagnetic radiation found in the home has to have been judged safe by govermental bodies, otherwise it wouldn't be sold!!\n\nJust be wary of getting too close to microwaves if you have a heart pacemaker.

Okay time for a serious answer. \n\nNo it's not bad for your health. And you won't go blind or anything else, in fact tests have shown that it will keep your **** operating better. But many people won't tell you this becasue they don't want you "playing" with it.

Be careful.\n\nThat environment can be dangerous.

Nonionizing radiation is electromagnetic radiation that includes: \n\nRadio waves \nMicrowaves \nInfrared light \nVisible light \nHazards of Nonionizing Radiation\n\nUnlike ionizing radiation, nonionizing radiation does not have enough photon energy to remove an electron from an atom. However, it can still be hazardous. For example: \n\nPowerful industrial lasers, which emit tightly focused or coherent beams of visible light, can burn through human tissue and even metal. \nSome nonionizing radiation can interfere with the operation of heart pacemakers and other medical devices, as well as critical equipment in aircraft. \nHigh levels of radio frequency and microwave radiation can heat tissue and if the temperature increase is high enough, can adversely affect health. \nElectric and Magnetic Fields\nExtremely low-frequency electric and magnetic fields (EMFs) surround electrical machinery, home appliances, electric wiring, and high-voltage electrical transmission lines and transformers. (Figure 11) \n\nA good deal of public and government attention has been focused in recent years on the possible health effects of EMFs. The public is exposed to these fields through the generation, transmission, and use of electric power. The National Institute of Environmental Health Sciences (NIEHS), a branch of the National Institutes of Health (NIH), has compiled information on this issue. (You can get more information on this and other issues from the NIEHS Web site http://www.niehs.nih.gov/emfrapid) \n\nHigh-voltage power transmission and distribution lines have been a major focus of concern. Alternating-current (AC) electricity, with a frequency of 60 cycles per second, falls into the extremely low frequency range on the electromagnetic spectrum and thus has far too little energy to cause ionization. \n\nHowever, AC electric and magnetic fields can induce electric currents in conducting materials, including human and animal tissue. (Direct-current fields, such as the Earth's magnetic field, do not have this effect). The electric current induced in our bodies may have potential biological and health effects. \n\nEvidence of health effects from EMF is inconclusive, although some studies have indicated a possible link between EMFs and childhood leukemia and other forms of cancer. The information available, however, is not sufficient to establish a cause-effect relationship. \n\nSome studies have reported the possibility of increased cancer risks, especially leukemia and brain cancer, for electrical workers and others whose jobs require them to be around electrical equipment. Additional risk factors, however, such as exposure to cancer-initiating agents, may also be involved. \n\nSome researchers have looked at possible associations between EMF exposure and breast cancer, miscarriages, depression, suicides, Alzheimer's disease, and Amyotrophic Lateral Sclerosis (ALS, or Lou Gehrig's Disease), but the general scientific consensus is that the evidence is not yet conclusive. \n\nIn June of 1998, a special review panel convened by the NIEHS reviewed EMF health studies. A majority of the panel found "limited evidence that residential exposure to extremely low frequency magnetic fields may increase the risk of childhood leukemia." A majority also found limited evidence that workplace exposure to EMFs may cause chronic lymphocytic leukemia in adults. \n\nAccording to NIEHS, "the probability that EMF exposure is truly a health hazard is currently small. The weak epidemiological associations and lack of any laboratory support for these associations provide only marginal scientific support that exposure to this agent is causing any degree of harm." The NIEHS did conclude, however, in its 1999 Report to Congress, that extremely-low-frequency EMF exposure cannot be recognized as entirely safe because of weak scientific evidence that exposure may pose a leukemia hazard; the associations reported for childhood leukemia and ad

Lightning can and does strike houses, but seldom with any injuries or fatalities. Stay away from electric appliances, electrical outlets, exposed plumbing, and don't talk on the phone unless its cordless. Never take a bath or a shower during a thunder and lightning storm. Avoid windows, and unplug the power cords to your computer, including the telephone cable going into your modem.

High frequency radiation like ultraviolet radiation contains more energy, and it can damage the DNA in your cells, causing cancer. \n\nIt can also cause bad burns.

There are two major things that can happen to you when you are electrocuted.With enough voltage your heart will go into a lethal rhythm that can only be corrected with "shocking" by a health professional. A serious burn can also occur if the voltage is high enough.She probably threw up because it scared her to death.The choice to take her to an e.r. is up to you.Place plastic caps in receptacles for child safety.

I checked out those links.  It looks like a bunch of BS to me.  (FWIW, I have a BS in Physics with 33 graduate hours in Physics and a Masters in Science Ed.)\n\nFirst, the facts:  Electromagnetic Fields (EMF) are produced whenever electric charges are in motion, i.e. in all electrical devices.  Light rays are one form of EMF's.  We already know how to protect against those: Wear sunblock.  \n\nBut the EMF's that we're talking about here are radio frequency EMF's, which are much lower on the spectrum, and thus have much less energy.  The EMF's that have caused concern in the medical field are Extremely Low Frequency radio waves such as those produced by power lines.  When electricity is moving down the lines, oscillating back and forth 60 times a second, it sends off these low frequency radio waves.  Some epidemiological studies have associated long term exposure to these ELF radio waves with childhood leukemia.  This is still controversial, however, and the US EPA has not issued any official position about EMF exposure.\nIn any event, with power lines we're talking about constant exposure to relatively high (1 mG) EMF's.  You wouldn't get that from your home computer unless you parked yourself within 4 inches of it for 24 hours a day.  Remember, EMF's drop off in intensity as the square of the distance, e.g. doubling your distance reduces them by a factor of four, tripling the distance reduces them by a factor of nine.\n\nAnyway, the only real way to shield something from low frequency EMF's is to completely enclose it in a metal box or wire mesh.  These things are essentially versions of what physicists call a Faraday Cage.  The idea is that the metallic condutors absorb the EMF's so they don't penetrate the cage.  Radio engineers protect sensitive radio equipment this way.  Security experts do the same thing the other way around.  Radios, TV's and even computers and electric typewriters produce minute radio waves that can be picked up by very sensitive receivers, so to prevent spies from finding out what's going on in sensitive government sites, they shield them in metallic conductors.\n\nThe device your links show clearly does not surround you, so it can't be effective in shielding from EMFs.  All the talk about sympathetic oscillations is true but meaningless.  Any piece of metal does that; that's how antennas work.  An antenna is just a piece of metal; when a vibrating EMF hits the antenna, the electons start to vibrate in synch with it.  IOW, you could get the same result as these devices claim by just wearing a piece of metal on your chest.  The claims about blood flow, "healthy energy states", etc. are just nonsense.

Its no more dangerous than using your home computer.  There are microwaves emmitting from everything from your monitor to your tv to your microwave oven to portable phones.  If you use those things and have no reactions then you will have no reactions to wifi either.

Proper Voltage of Tolerance that a body can take is not harmful, but more than the tolerable can get body organs cooked.  \nElectricity never reamsin in the human body it just pass through.. for a brief millisecond...\n\n-- Hope this helps.. Goodluck =)

Besides the addiction of watching everything that's "on now" which sooner or later creates sedentarism, Tv-sets, especially those build on a cathodic tube transmit radio waves which are harmfull for our eyes. Scientist say that we should keep a minimum distance of 40-50 cm from the TV-set but even so it's dangerous (if we watch it almost non-stop). \nThe new technology, based on liquid crystal (or LCD) and pasma technology were build to remove those waves and thus reduce the damage to the eye.

Very very dangerous. Potentially fatal.

mobile phones use the spectrum below the visible wave length  (  and below IR  ) . those frequencies have low energy typically (though MW is used for cooking...) and are not considered of the ionizing radiation type, which is on the other side of the spectrum ( above UV ). For example: X rays, Gamma rays, etc'...which are definitely dangerous. Nonetheless I'd use a cautious approach and common logic when using any radiating device which has only been around for a few years . if there are negative effects we shall see them years from now on the "heavy users" of cell phones...\nanother issue is that those tumors i guess you're referring to occur because of DNA braking up during transcription by exposure to ionizing radiations ( which has a short enough wave-length ) , that could most definitely NOT occur with your cell phone!\n\nso my answer is - NOT LIKELY.

Your concept of the linesman is correct, however, being immersed in a body of water is dangerous.  Lightning carries a far greater potential than that of what the linesman faces.  True, there is no conduction of current to ground, but the copter and the line must be equalized before contact can be made.  This is because of the state of "STATIC ELECTRICITY".  Energy that is "Static" is not moving.  Nevertheless, when it comes in contact with another object, one who's energy level is at a different potential, the energy no longer remains static.  The sudden rush of current will be felt.  That's why when you cross the rug and grab the door knob you get a shock.  You have a significantly higher potential than the door knob and when you touch it there is a rush of energy trying to equalize the differences.\n\nBeing in a pool at essentially zero volts and a crack of lightning hits close by, the ground and the water in the pool will charge up before dissipating the lightning strike, possibly leaving you dead.  Wouldn't that ruin your day?\n\nDuring lightning storms stay out of the pool or the tub, do not be running the sink and stay off the phone (cordless phones do not apply in this case as there is no direct wiring to the outside world).  There have been documented cases where persons on the phone have been struck in the head by lightning, again it's due to that equalization of energy levels thing.\n\nHey, even if everyone is wrong, wanna risk your life?  You could die in a tub if someone dropped something electrical in the water.  True, your assumption is that water conducts better than the human body, but that is a wrong assumption.  Pure water is an insulator.  It's the impurity in water that makes it conduct.  Our bodies are actually much better conductors of electricity.  Don't believe me?  Ask someone like an electric shop teacher.\n\nI hesitate to give you a test to try because of the danger of electrocution, but if I were at your house I could demonstrate in a matter of seconds that what I am saying is true.  But for the sake of not causing someone to try a potentially dangerous experiment I'll not be specific.\n\nHowever, if you must know, e-mail me and we can chat.  When I am confident of your ability to conduct the test safely then I will tell you how to do this.

It is possible to have too many waves going into the brain in too short of a period of time...\nNow if you were dying anyway and had nothing to lose, then by all means, if you wanted to help science you should do so and get paid well to leave something for your family...\nHowever, it is not a good idea if you are doing it just for fun or for the money...\nIt could alter your brain wave pattern in some way we may not be equipped to understand yet...
