The radiation waves emitted by computers are often ignored. According to the international MPR radiation safety regulations, the radiation exposure within 50cm distance must be less than or equal to 25 V/m..
But do you know how much radiation the computer has? Computer radiation: 1, keyboard 1000V/m2, mouse 450V/m3, screen 2 18V/m4, host 170V/m5, notebook 2500 v/m.
A British study confirmed that low-frequency radiation and magnetic fields emitted by computer screens can cause 7- 19 diseases, including itchy eyes, neck and back pain, transient memory loss, irritability and depression.
Computer radiation is also easy to cause abnormal reproductive function and embryonic development in women. According to the investigation of more than 200 computer operators in Wuhan banking system, more than 35% of women have symptoms such as dysmenorrhea and prolonged menstrual period, and a few women have premature delivery or abortion. According to the research of the World Health Organization, if pregnant women use computers for more than 20 hours a week, the incidence of abortion will increase by more than 80%, which may also lead to fetal malformation.
Among them, when the eyes are itchy, dry and sour, the eyes are only in the stage of functional injury. However, if we don't pay attention to protect our eyes at this time and make them dry for a long time, it will lead to corneal epithelial cells falling off, causing organic damage, further aggravating symptoms and seriously affecting our vision.
Cervical dorsal syndrome caused by long-term tension or injury of neck muscle and soft tissue will develop into cervical spondylosis if it is not treated in time.
Women who have been engaged in computer-related work for a long time have a higher risk of breast cancer than non-computer workers. This is a survey in Taiwan Province Province. At present, there are more than 3 million computers in Taiwan Province Province, and most of them are women. If you work in front of the computer for a long time, it will increase the risk of breast cancer; Premenopausal women are more likely to develop breast cancer than postmenopausal women. After the reproductive health of professional women is damaged, the main manifestations are menstrual disorder, pregnancy-induced hypertension syndrome, early menopause, decreased fertility, spontaneous abortion, low birth weight, congenital malformation and even fetal death.
The most radiant part of the computer
The radiation on the back of the computer is the strongest, followed by the left and right sides, and the radiation on the front of the screen is the weakest. So try not to let the back of the screen face someone, and the distance should be at least 50 cm to 75 cm, which can reduce the harm of electromagnetic radiation.
