- Q:LCD splicing screen how much electromagnetic radiation, how much light radiation
- Generally 450-500cd / m2, 700-800cd / m2 more, suitable for indoor projects
- Q:The picture shows the mobile device on the external walls of the dormitory, RRU, power supply and switches, etc.,
- Radiation, of course, the phone is much, the radiation is too big you say that the wireless device switch radiation
- Q:Computer generated by the current harm to the human body please you 3Q
- Third, the computer distributed the gas to harm the respiratory system. Researchers at the British Allergy Foundation believe that office equipment will release more or less harmful to human health of ozone, and here that the office equipment mainly refers to computers, laser printers, these ozone gas is not only toxic, and may cause a Some people have difficulty breathing, and the situation is more serious for people with allergies and asthma. If the long time to stay in the ozone gas concentration of high places, but also lead to lung lesions. Four is to increase the mental and psychological pressure. Operation of the computer process of high concentration of attention, eyes, fingers quickly and frequent movement, so that physical and psychological overburdened, resulting in neurasthenia, head soreness, dreams, decreased body immunity, and even induce some mental illness. This is the question you are asking.
- Q:Radiation of electrical radiation
- In addition, according to the recent China Environmental Monitoring Center announced the indoor appliance radiation rankings, seven commonly used appliances, the microwave ranked first, more than twice the national standard of radiation. When is the maximum mobile phone radiation? By the Chinese Consumers Association and the China Institute of Metrology jointly commissioned by the China Institute of Metrology found that the phone in the call out with the initial contact with the network within a few seconds, the largest electromagnetic radiation, the first ring after the ring, the radiation gradually reduced The The test results also show that CDMA radiation is significantly less than GSM; built-in antenna is smaller than the external antenna, but the built-in antenna phone back electromagnetic radiation than the front plate several times;
- Q:Does the computer have radiation in pregnant women after sleep mode?
- Q:Is the LCD radiation of the LCD screen within the safe range?
- Desktop computer host radiation index: ★ ★ ★ ☆ ☆!
However, the next test is not too optimistic, subwoofer speakers, the operation panel center, from 0.03 meters, 0.63μT; speaker right side of the central, from 0.03 meters, 5.68μT; radiation, but not small, that it What is the safe distance? After careful testing found that when the distance of 0.4 meters, its radiation is reduced to 0.17μT. So subwoofer loudspeaker serious radiation, use at least half a meter to keep the distance.
Subwoofer speaker radiation index: ★ ★ ★ ★ ☆?
The last thing to say is the laptop, the display before the 0.1 m 0.13μT, 0.3 meters before the display 0.10μT, 0.3dB 0.13μT on the side of the display, the top of the keyboard 0.19μT, power adapter 0.22μT. Test results show that the notebook keyboard radiation slightly stronger, the largest power adapter.
Notebook radiation index: ★ ☆ ☆ ☆ ☆
Note: the LCD screen radiation is very small, CRT monitor slightly larger, but are in the security range; host behind, side radiation larger, it is strongly recommended that you do not want to heat for easy, open the chassis; subwoofer loud noise, when used At least half a meter away; notebook radiation concentrated in the top of the keyboard, the use of notebooks and power adapter should be kept away from the distance.
Hey, right, light that the computer and notebook radiation is not, but that optical mouse for a while red blue is very scary, there is radiation? That wireless mouse, wireless keyboard is not the radiation than the ordinary to small it? There are wireless LAN launchers! There are digital equipment, what digital camera,
Tell you, this kind of battery DC electric appliances is the most secure
Ordinary mouse ordinary keyboard wireless mouse wireless keyboard wireless gateway printer digital camera and MP4 power adapter
- Q:Does the 400V cabinet have radiation?
- Any electricity equipment, there are radiation. Mobile phone radiation, the TV has radiation, the light has radiation, the computer has radiation, the refrigerator has radiation, rice cooker has radiation, as long as the power is connected to radiation.
- Q:Computer, television, mobile phones, microwave radiation is how much, what harm to the human body
- Hair dryer radiation index: ★ ★ ★ ★ ★
Another point to remind you that the power wiring board, if no electricity equipment connected, the distance of 0.03 meters, its radiation is only 0.11μT, not large; but in high-power electrical equipment connection, the distance of 0.03 meters, Its radiation may have 1.25μT. This may cause your attention.
Power supply wiring board (use state) radiation index: ★ ★ ★ ★ ☆
Text: Vacuum cleaner and hair dryer radiation, iron is not small, the use of children should be far away from the power wiring board radiation should also cause your attention, do not put it on the bed.
Electric foot basin, treadmill, fat sports machine
This is now popular electric foot basin, let us see how much radiation it? From the power line 0.03 meters, 2.20μT.
- Q:Mobile phone radiation or TV radiation?
- The radiation of the phone is bigger than the TV really ah mobile phone radiation is very obvious ah people will be difficult to improve the pathogen rate ah
Mobile phone radiation in the end is harmful or harmless, experts have been arguing over the years. Generally believed that the phone's electromagnetic waves are weak, minimal impact on the human body. However, according to the German "Bild" reported on the 8th, the EU scientists recently confirmed the results of mobile phone radiation can destroy cells and human genetic information with DNA.
Twelve research teams from seven EU countries conducted a three-year study on the impact of electromagnetic fields on human cells. Experts have determined that if the cell phone for each kilogram of human tissue radiation value greater than 1.3 watts, it will cause damage to human genetic information, and now the radiation limit is 2 watts per kilogram. In addition, the electromagnetic field will make the body produce a harmful protein.
"The radiation from mobile phones would destroy human inheritance, but whether it would hurt our organs," said Fitznell, a journalist from the Franklin University Hospital in Berlin. "We have not yet found evidence in this area." Professor Rudygel from Vienna suggested: "Please do not take risks for your own health, if possible, call your phone as little as possible; if you have to use it, please use your phone next to the house or window, or use a headset So that radiation does not come into direct contact with the brain.
- Q:Light, heat, sound, electromagnetic waves, these radiation, which radiation damage
- Electromagnetic wave
Light, heat, sound these are relatively weak radiation, the largest damage belongs to the electromagnetic wave!
