However, the amount of radiation you know the computer is? Computer, the amount of radiation: 1, keyboard 1000V/m2, mouse 450V/m3, screen 218V/m4, host 170V/m5, Notebook2500V / m
In addition, electromagnetic radiation on the human body has eight major injuries:
."
Degree from harm, without doubt, the biggest hazards of electromagnetic radiation. Domestic and foreign medical experts, research shows that long-term, excessive electromagnetic radiation harmful to human reproductive system, nervous system and immune system causing direct damage to cardiovascular disease, diabetes, cancer, mutation and cause a major incentive for pregnant women, abortion, infertility, abnormal fetal diseases such as inducing factors, may directly affect the minor's body tissues and bones, causing vision, memory loss and decreased liver hematopoietic function, can lead to serious retinal detachment. In addition, electromagnetic radiation also causes of information security risks, using a special signal reception equipment to receive can be cracked, resulting in leakage of information caused unnecessary losses.

Away from the screen, the closer, the greater the electromagnetic radiation received by the human body, so good is half a meter away from the screen.
Computer use, will face a lot of electromagnetic radiation absorption of particles, to promptly wash with water, so that would reduce the radiation suffered 70%.

To be able to see clearly the word prevail, at least 50 cm to 75 cm distance, thus reducing the harm of electromagnetic radiation.
Attention to indoor air: research confirmed that the computer screen to produce a brominated dibenzofuran known carcinogen. Therefore, the best place to install the computer room ventilation fans, if not, with particular attention to ventilation when the Internet.
The face of the computer a long time is not good, then how to do? In fact, four cups of tea a day can not only fight against the radiation, but also protect the eyes.
