Do Wired Headphones Emit Radiation?

Whether mobile phone radiation is harmful to health, this is still a heat debate among individuals. People also wonder if the wired earphones emit radiation.

Cell phones and radiation

Radiation is simply energy produced by an object; a broiling steak emits infrared radiation from its heat, for example. Mobile phones produce radiation from the radio waves they transmit. Scientists distinguish radio waves, infrared and visible light from more harmful radiation such as X-rays and alpha particles; the latter have far more energy and quickly damage living tissue. Radio waves do not produce harmful effects in the short term; they may cause harm after several years' worth of exposure, but the evidence has not yet shown a clear connection between cell use and cancer.

Wired headsets and radiation

A wired headset is an earpiece-microphone device that fits on your ear, and connects to your phone via a wired cable. These do produce radiation, as does any wire that carries an electric current. However, the radiation from a wired headset results in weak radio waves at audio frequencies -- difficult to detect, even with sensitive equipment, and several orders of magnitude weaker than the radio signal the cell phone produces. Using a wired headset is one of the safest solutions available for cell phone users.

Recommended practices

You receive the strongest radiation dose from a cell phone when you hold it to your ear because it is close to your body; distance reduces any radiation hazard. With a headset, you can put the phone on your desk or car console, moving it away from your body to decrease your exposure considerably. A wired headset contributes very little of its own radiation. You can achieve a similar reduction by using your cell's speaker function.
