    Does inverter batteries emit any radiation that are hamful for health ?

    i have a inverter in my home, i use to work very close to it, i want to know that does it emit any radiations? being working very close to it i fell a continuous headache and pain in my legs, does it due to radiation from batteries?

    Ergonomics?

    Not likely.

    I'm not sure what you mean by radiation.

    An inverter and battery will produce infrared radiation. This is called heat.

    An inverter with an on light will produce light. This can be stopped by a piece of black tape or chunk of cardboard.

    An inverter and battery will produce alpha, beta, and gamma radiation. Alpha radiation will be stopped by your clothing. You can stop beta radiation by putting the inverter and battery in an aluminum box, but then you have a new source of beta radiation namely the box. Stopping Gamma radiation is very difficult, the best way is to use old chunks of battleship armor which was made prior to any atomic explosions.

    An inverter and a battery (when in use) will produce electrical fields. These can be stopped by the aluminum box.

    An inverter and a battery (when in use) will produce magnetic fields. These can be stopped by the chunk of battleship armor or a steel box.

    Basically all of these radiations are present all the time everywhere. One or more may be heightened near the inverter and battery.

    I am not a medical doctor, perhaps you should see one or an occupational hygienist concerning you problem. Or it could be as simple as a non ergonomic arrangement of your chair, desk, and work.

      Mechanical radiation, aka "sound", is a more likely culprit. Inverters now use a technology called PWM (Pulse Width Modulation) in their design, what is known as a Switch Mode Power Supply (SMPS). Actually, the SMPS concept is used now in almost all electronics, it is what allowed designers to make things even smaller again after transistors came into use instead of tubes. In an SMPS, transistors are fired at very high rates, as in 1-15kHZ, and various combinations of on and off times, fired into inductors, allows the transformation of power with very little space needed or heat generated. But in that process, the transistor firing has an effect of making the inductor components vibrate mechanically, which produces a high pitched sound. Remember the hearing tests you were given as a child, where you put on headphones and told the nurse or technician if you did or did not hear a tone? Those tones are created by PWM, and are the same thing that comes off of all SMPS based devices. So the PC you are using has an SMPS, the monitor has an SMPS, the phone charger has an SMPS, the TV in the room has an SMPS, LED and CFL lamps are all using SMPS inside, all of them emmitting high frequency sound. If you have an inverter (whatever that might be), it too will be an SMPS. It is entirely possible that the multiple SMPS devices in your environment are emitting complex sound patterns that, even if you don't "hear" them, are nevertheless having an effect on your auditory nerves. Adding the inverter might just have been the final straw in a big pile of hay.

      Simple answer, try moving everything around, envisioning each of them as a sound generator, so you can locate them in ways that might disrupt any resonant frequency interactions. I used to get migraines so I had to do that, it worked wonders. The more powerful the device, the more powerful the sound pressure coming from it, so I started by putting my UPS under the desk, that made the most difference. I then moved most of the "wall wart" power supplies for various things to one of those "squid" power taps and put them behind my desk by pulling it away from the wall a little, then filling the gap with a board. The only SMPS devices on my desk now are the laptop itself and my desk lamp, because it is LED and has a USB charger port built in. My migraines have never returned.

      By the way, it will have nothing to do with batteries, other that to keep the batteries charged, the charger will be..... an SMPS!

        Jraef brings up a good point, that could be easily overlooked.

        If it is auditory nerve stimulated problems you are having, just to see if it causes changes in symptoms try using headphones (probably not loud rock music for long periods either) or ear plugs to see what kind of response you may experience. This may not work if blocking out external sounds will be a problem with some of your work responsibilities. Many of us have just the opposite experience though and maybe are even required to wear devices that will block machine noises or other work environment noises because of the potential threat to cause hearing loss.

          You pet dog and your pet rock emit radiations that some claim are hazardous to your health.

          As a good general rule it's a bad idea to work for prolonged periods of time near any powered machine.
          The bad effects begin with noises both within and outside human hearing.
          They continue with vibrations particularly with rotating equipment but include powered devices.
          Both of those will eat at your health long, long, long before any traditional electromechanical energy.

          Oh, and an observation. A lot of folks that work close to such equipment due so because they're otherwise out of room.
          Consider whether you're getting enough room to stretch and move.
          Being crammed in a small space can cause migraines and such.

          The last thing you should worry about is whether the inverter is giving off radiation.

            Sound

            The Digital Equipment Corp (DEC) produced the VT100 series of display terminals (Display and Keyboard). They were designed by older male engineers who loved them. The young secretaries hated them, gave the headaches. It turns out that that they emitted a tone of about 15kHz. The engineers could 't hear it and the secretaries could.

              Don't work in front of it, I don't have the idea that whether this headache and pain in legs is because of the radiation or not, but as inverter inverter also generated the heat so, its not good for the health.

                  Sort of more like belonging to Dr. House don't ya think?

                  "Maybe you should get yourself a real desk instead of working on top of the inverter. Your headaches are from lack of sleep and that constant hum of the inverter. Your legs ache because you've got them crammed underneath you for long periods of time. Tell ya what, take two of these lemon drops I've substituted into your Vicodin bottle. Stop by when you need a refill."

                    I think it is probably an ergonomics problem. The idea that it is sound is a close second. A tin foil hat doesn't help with either of these.

                      we could suggest wearing an induction suit..... with a #12 grounding strap....

                        I think it is nonsense.

                          What would having it made prior to any atomic explosions have to do with anything?

                          Lead or concrete or other dense materials will reduce alpha, beta, and gamma radiation.

                          There is no "stopping" radiation. There will always be some minute amount that makes it way through the shielding. The goal is to reduce the particle velocity and quantity to a level where it isn't likely to cause harm. For example, you might reduce it until its below the natural background radiation level.

                          I would expect the radiation from an inverter and batteries to be much less than the background level to start with. So shielding would be kind of pointless.

                            I think that the issue, at the trace radiation level, is that the level of radioactive isotopes in the environment (i.e strontium, cesium, iodine, etc. ) is far higher since atmospheric testing began than it ever was from purely natural sources.
                            So for some scientific experiments you could stop all (almost all) of the incoming gamma rays but replace some of them with emissions from contaminants in the steel itself.

                              Precisely. Battleship armor pre-1940 is prized by researchers who are measuring low levels of radiation because it is less radioactive than post-1960 steel.
