With the rapid development of science and technology, computer and internet are widely used, and then play a very important role in people's daily life, work and study. Though the computer brings much convenience to our life, it also causes radiation problem. The radiation waves released from computer mainly refer to electromagnetic radiation, a radiation usually has effects on biological systems by stimulatory effect, heating effect and non-heating effect. The radiations generated by a computer at work include electromagnetic radiation (electro-magnetic radiation and electromagnetic waves), sound (noise), light (ultraviolet, visible and infrared radiation, etc.) and other radiation "pollutions", and affect the body's nervous system, immune system, circulatory system and development of life functions. Tungsten alloy computer shielding is the best solution to these radiations.

For all humans exposed to radiation ,women, frail elderly persons and children are the most sensitive to computer radiation , especially the fetus. According to the research, long-term acceptance of computer radiation is thought to increase the risk of fetal malformation. Computer radiation can also lead to hair loss by giving rise to the endocrine disorder. Increased levels of sebum excreted from sebaceous glands would clog follicles which then lead to hair loss. What's more, computer radiation can damage the eyes, mild damage, dry eyes and eye fatigue; moderate damage, a clouding of the lens of the eye, impaired vision; serious damage , cataract, vision disappeared. Computer radiation can through the retina to lens with its very high penetration, and produce free radicals, to result in death of human retinal pigment epithelium, and to lead to the photosensitive cells lack nutrients, then causing impairment of vision. Computer radiation is the main culprit of blindness - macular disease.

Computer radiation is inevitable, but can be reduced, one way is to use a tungsten alloy computer shielding. The major function of tungsten alloy computer shielding is to shield the computer radiation to protect users from the radiation damage.
