2 thoughts on “Is there any harm to human body in the computer room?”

Physics tells us that any objects with higher temperatures than absolute zero will generate radiation. At the same time, humans have not found any objects that are equal to or lower than absolute zero. That is to say, although radiation is both not visible nor touched, it is common in life. Whether it is watching TV, sun exposure, plane or shooting X -rays, everyone cannot avoid radiation. Of course, most of these radiations do not harm the human body. Suppose that a person goes to work for 300 days a year, and passs the security instrument twice a day. The total radiation in the whole year is only 1/14000 of the safety standard. Even if the lead curtain of the security check is severe, the total radiation of this person throughout the year is only 1/120 of the safety standard, and the impact on health can still be ignored.
The almost everyone has a mobile phone, and the transmission of the mobile phone signal is inseparable from the base station. For a while, it is difficult for mobile phone operators to find the location of the establishment of a base station because people are beginning to worry that the radiation of the base station will affect physical health. During the stalemate, the test results of scientists played a role -although the base station launch power is larger than that of the mobile phone, because the mobile phone is closer to the human body, the most
is still more radiation generated by the mobile phone. More importantly, no matter what kind of mobile phone radiation, it is actually within the safety standard. For computer radiation, only the screen is turned off without turning off the host. The computer radiation still exists, because the components in the computer case will also generate radiation. Putting a cactus next to the computer, it will not absorb or shield the computer radiation. The easiest way is to drink 2 to 3 cups of green tea every morning. Green tea can not only eliminate the harm of computer radiation, but also protect and improve vision.
compared with radiation, the radioactivity seems to be even more smelted. When the atomic nucleus transforms the structure or energy state, particles or electromagnetic waves are emitted, including α rays, β -rays and γ -rays. After they invade the human body too much,
This may interrupt the DNA chain or change the structure of DNA molecules, causing DNA to mutation. In severe cases, it also increases cancer, distortion and hereditary lesions, and even affects the health of generations. At present, humans have found 109 yuan
, 92 of which are existed in nature, and only 17 kinds of manual manufacturing, so it cannot be said that all radioactive phenomena are caused by artificial phenomena.
As far as I know, the radiation in the data center machine room should be electromagnetic radiation, and the source of radiation is very wide. The first is from the outside of the data center, such as the surrounding radar, radio launch equipment, mobile telephone base stations, high -voltage wires, electrified railways, etc. will generate radiation, and there are some extreme weather, such as lightning, high temperature, haze and other weather. Radiation; followed by the data center, such as the power distribution box, high -power motor, high -frequency switching power supply, air -conditioning equipment, and periodic pulse -type electromagnetic radiation generated by various electronic equipment, as well as various internal cables and fiber optic fibers , Cabinet, power supply, etc. also generate electromagnetic interference signals. Therefore, electromagnetic radiation is everywhere in the data center.
During the physical class, the teacher should have said that the electromagnetic wave has direction. The electromagnetic wave superposition in the same direction, the radiation intensity increases, the electromagnetic wave superposition in the opposite direction, and the radiation intensity weakens. The intensity, distance and frequency of electromagnetic radiation are related. The farther the distance, the weaker the strength, the higher the frequency, and the greater the energy.
The frequency of general transmission and transformation equipment is 50 Hz, which is extremely low frequency. 50 Hz's industrial frequency radiation has become an electromagnetic induction. Its radiation nature is weak and will not endanger human health. If the frequency of the device exceeds 50 Hz, or even thousands of Hz, the electromagnetic radiation it produces may cause some harm to the human body. In order to improve the efficiency in some large and medium -sized data center computer rooms, there are more and more high -frequency devices, such as high -frequency UPS, etc., and because there are many electromagnetic radiation sources inside the data center machine room, this will be overlapped multiple times. It may produce some strong radiation waves, and these radiation waves are inestimable to cause damage to the human body.
The electromagnetic radiation has many damage to the human body. Research by medical experts at home and abroad shows that long -term and excessive electromagnetic radiation will cause direct damage to human reproductive systems, nervous systems, and immune systems. It is the main cause of cardiovascular disease, diabetes, and cancer. Promoting factors such as tires and other lesions.
The electromagnetic radiation can also cause fierce loss of calcium ions in the human body, caused by dementia, and can directly affect the development of body tissues and bones of minors, causing vision, memory decline and liver hematopoietic function. In severe cases, the retina can fall off. Excessive electromagnetic radiation will also interfere with other surrounding electronic equipment, affecting its normal operation and the problem of electromagnetic compatibility (EMC).
