For Health, Turn off the lights already blinking

If the lights in the house have started blinking or a harbinger of death should be immediately shut down or replaced. It's for your health, because the blinking lights could potentially emit X-rays that are harmful to the body.

"Blinking light will radiate more power than the lights that remain lit. It also has the potential to emit X-ray radiation," said Dr. Bayu Gede Suparta, researcher and lecturer in the Department of Physics University of Gadjah Mada University, Yogyakarta, when contacted detikHealth, Tuesday (22/06/2010).

According to Dr. Bayu, when the lights flashing then there is an event known as bremsstrahlung, ie the term in German for braking radiation.

At the time the lights begin to flicker, the electrons will move at the speed of high energy. But the condition of the lamp is going to die, the electrons will be braked suddenly because mashing metal atoms (copper, copper, iron, aluminum) in the lamp.

Well, when there is comminution of metal atoms that cause X-rays called the X-ray bremsstrahlung. Although X-ray energy emitted is not too large, it still can be harmful to health if left too long.

In physics, electromagnetic theory says that an accelerating electric charge will radiate electromagnetic waves, ranging from the smallest power of radio waves, infrared, visible light, UV, X-rays or gamma rays.

"When the lights are still working normally, the electrons will strike a neon gas serapannya smaller. Because there is not braking, then the emitted energy was low, so that the light emitted is visible or visible as fluorescent lamps," said the lecturer, who also chairs Physics Research Group Image (GRFC) Department of Physics Faculty of Mathematics and Natural Sciences, UGM.

The energy of visible light is smaller than the X-ray energy, then the blinking lights that emit X-rays is far more dangerous than the lights continued to burn and emit light.

Although X-ray exposure is not a disease, but its impact is very big because it can lower a person's immune system that makes so easily affected by the disease. X-ray exposure can trigger even suspected cancer risk and make stunted fetal growth.

Dr. Bayu is still active in the Institute for Research and Community Service (LPPM) UGM also said that the purple lights should not be used as a lamp of learning.

This is because visible light purple that has a shorter wavelength, even at times almost equal to the wavelength of UV that is harmful to health.
