10 "all" electromagnetic radiation
Rapid scientific and technological development in various conveniences to our lives, but also may bring some hidden damage. When we use computers, listen to MP3, watch TV, take a cell phone, the electromagnetic radiation they go hand in hand. Get along with them too long, it may cause to our health violations.
Not just mobile phones, computers, home appliances and other electronic equipment, even the neon lights are interfering signals may be issued, the busy people of the brain abnormalities can not rest, resulting in headaches, mental tension and stress symptoms, which arise due to excessive electromagnetic electronic products radiation on human health impacts, it was also called "e-disease."
Glossary
What is electromagnetic radiation?
Any charged exists an electric field around the body, periodic changes in the electric field will produce periodic changes in the magnetic field, the existence of electromagnetic waves to produce electromagnetic radiation, electromagnetic radiation caused by excessive electromagnetic pollution. Some transmission equipment, microwave equipment, household appliances, modern office equipment, high-pressure transmission and distribution systems, are likely to cause electromagnetic pollution. Divided by the frequency of electromagnetic wave: long wave, medium wave, shortwave, FM and microwave. In general, the long-wave effects on the human body is weak, the shorter the wavelength the higher the frequency, greater impact on the human body, the most prominent effect of microwaves.
TV, home computers are electromagnetic waves emitted by ultrashort wave, microwave ovens, mobile phones and other communications using electromagnetic waves are emitted when the microwave category. ??
Status
Radiation into the computer the quality of Yinji
By the State Administration of Quality Supervision latest national quality supervision and spot check the computer results show that the domestic market in the computing speed of computer products, multimedia capabilities and in terms of hardware and software support has been greatly improved than before, but some companies to stabilize the level of product quality. Electromagnetic compatibility of some products in the radiated emission, conducted emission targets exceeded.
Radiation harassment is a computer work as a space launch to electromagnetic interference, such interference will affect the other electrical appliances, especially high sensitivity of the normal work; conduction disturbance in the same network will be affected the normal operation of other appliances, such as composition of the whole system motherboard, video card, switching power supply, monitor, keyboard, mouse, etc., if the purchase would give rise to radiation disturbance well exceeded. ??
Electromagnetic radiation into a new source of pollution
Medical research shows that long-term, excessive electromagnetic radiation harmful to human health injury, vision, memory loss and other phenomenon. Electromagnetic radiation has been following the World Health Organization as water, air, noise, the fourth largest source of environmental pollution, a hazard to human health elements.
Most contact with our computers used, for example, the terminal is a CRT computer monitors and television sets as its principle, when the cathode ray tube emitted electron flow impact on the screen, they can transform into visible light , in the process will produce harmful X-rays. But also will produce low-frequency electromagnetic fields around VDT and long-term by the electromagnetic radiation pollution, affect people's health. ?
Strategy
10 electromagnetic radiation techniques
For computer electromagnetic radiation hazards, protection can be taken active and passive protection of two ways. Passive protection law is in addition to improving the working environment and pay attention to use of methods, to give regular contact with the staffing and operation of computer radiation suit, radiation protection screen, radiation protection curtains, glass, radiation protection measures to reduce or eliminate electromagnetic radiation injury; Active Protection Act, is the electromagnetic radiation from computers, "the source"?? display and chassis and other components to start, to eliminate or shield.
