May have heard the issue of radiation on equipment such as mobile phones or laptops electronic quite controversial. In truth, however, note that all electronic devices out of radiation that we can not avoid, from a TV, microwave, computer, and others. Yet as we know, the use of these tools seemed inevitable.
All electronic devices issued a similar electromagnetic field (electromagnetic field or EMF), which is one type of radiation. However, EMF is a type of non-ionizing radiation, or radiation that is not even enough energy to ionize atoms or excite the electrons, in contrast with the radiation of uranium, which is ionizing radiation.
Examples of extreme radiation from electronic devices is of the microwave radiation , which issued a field with high frequency which can be detected even within a few yards. But most other electronic means of radiation would be reduced within a few inches only. So long as we keep enough distance when using these tools, then there is no need to worry.
But there are cases such as the use of laptops. Many people put their laptop on the thighs when they work. That is, the distance between the body with a laptop is zero. Does this affect our body?
Radiation coming out of the laptop were mostly from the laptop components, such as hard drives and memory chips, rather than coming out of the screen / display.
Tranceiver (receiver) wireless connection also produce microwave radiation, so there is also alleged that says that the wireless signal (or wi-fi, wireless fidelity) is far more dangerous. But the WHO (World Health Organization) denied this and said that the effect is still below the limit which can damage the human body.
There are recommendations that limit the electromagnetic field that can be tolerated is 2.5 miliGauss body. However, the laptop was able to spend more than 150 mg when used.
Desktop computer equipped with a metal casing so as to form a protective Gauss protect of radiation. But on some laptop makers eliminate these protective of their product to their laptops lighter and more user interesting.
thanks for the great info
