computer radiation? Are pregnant women as sensitive people away from computers? The following data should be the most obvious: the Peking University Institute for reproductive health has been tracking 20 million children aged 7 years in the country since 1991. So far, experts have not found that the use of computers in pregnant women has a bad effect on the fetus.

professor Zhao Yufeng, an expert on indoor environmental monitoring of the China Interior Decoration Association, said that the main source of the computer radiation is the CRT (cathode ray tube) display, which produces low energy X rays when the high pressure electron gun is emitted from the high velocity particle flow to form an image. Electromagnetic radiation such as electrostatic field, radiofrequency electron field and so on. Although computer hosts, keyboards and so on also have different degrees of radiation, they are mostly caused by working circuits, and the radiation intensity is much lighter.
professor Zhao Yufeng said that although computer radiation exists objectively, it and electromagnetic pollution are two concepts. Only more than a certain intensity can produce negative effects on the human body. At present, the limits of safety and health standards for electromagnetic radiation in China are lower than 40 micro watts per square centimeter. As long as the computer produced by the regular manufacturers, the related tests are required, and there is no radiation problem in general. Professor Wei Tao, a researcher at the center for radiation protection and nuclear safety of the China Center for Disease Control and prevention, said: "the radiation of the computer is nothing, even lower than the color TV. Some people use computer time for a long time, appear dizziness, nausea and other symptoms, worry about the computer radiation, in fact, this is probably due to high concentration of work, too high pressure.

, is there any individual difference in the influence of computer radiation? Are pregnant women as sensitive people away from computers? The following data should be the most obvious: the Peking University Institute for reproductive health has been tracking 20 million children aged 7 years in the country since 1991. So far, experts have not found that the use of computers in pregnant women has a bad effect on the fetus. WHO experts have also said that there are many factors affecting women's pregnancy outcomes, mainly working fatigue and excessive tension, and the extremely low frequency electromagnetic field of the computer is only a secondary cause.
vice director of the Department of perinatal medicine of the Chinese Medical Association and Professor Yang Huixia, vice director of No.1 Hospital of Peking University, also said that so far, there is still no authoritative investigation to show that there is an inevitable connection between computer radiation and fetal health, and that pregnant women can relax their mentality as long as they are not in a large machine room or work. As a result of high-power radiation such as stations, daily use of computers will not affect pregnant women and fetuses. Juran, Professor of Obstetrics and Gynecology of Peking Union Medical College Hospital, also believes that there are many factors causing abortion and fetal malformation of pregnant women.
