(The correct answer is at the end of the article)
Carcinogenic spermicide is true or false
Mobile phone radiation is non-ionizing radiation. The energy of the radio wave is low and not enough to cause ionization damage to cells and cause cancer, but it will affect the function of cells.
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) believes that local exposure of the human body to radiation doses exceeding the limit will cause human body dysfunction, interfere with the physiological and electrical activities of the human heart and brain, cause poor sleep, and lead to vision loss and cataracts. wait.
Apple also tested the electromagnetic wave absorption ratio of the mobile phone when it was 5 millimeters away from the body. The results showed that the amount of radiation exceeded the upper limit of mobile phone radiation set by the US Federal Communications Commission (FCC) to regulate mobile phone safety. Imagine that when the mobile phone is placed close to the body, the amount of radiation received by the human body is greater.
Although there is still controversy about whether the incidence of brain gliomas increases among mobile phone users, on May 31, 2011, the International Agency for Research on Cancer (IARC) officially listed mobile phone radiation as a possible Carcinogenic level.
Impact on Health Children are more susceptible to "injury"
Compared with adults, children are more susceptible to the effects of electromagnetic radiation. The brain is the main organ exposed to cell phone radiation. Experts believe that the nervous system is not fully developed in children, and even low-frequency electromagnetic radiation can interfere with children's active electrophysiological activities and cause neuron damage.
The longer children and teenagers use mobile phones, the more electromagnetic radiation they will receive from mobile phones, and the greater the risk of damage to their bodies.
A prospective group study conducted on 234 teenagers found that the longer the teenagers used wireless devices, the greater the amount of electromagnetic radiation they received and their memory was tested through a cognitive testing system one year later. The greater the decline.
However, the WHO (World Health Organization) believes that the results of these studies on the effects of cell phone radiation on memory, learning and cognitive function are inconsistent; the most consistent health risks associated with cell phone use are distracted driving and vehicle accidents .
You can also reduce mobile phone radiation
It is almost impossible not to use mobile phones, but scientific use can reduce mobile phone radiation damage. In addition to minimizing the frequency and time of using mobile phones, you can also pay attention to the following A few points:
Avoid placing your mobile phone close to your body;
Do not place your mobile phone on the bedside when sleeping;
Try to use wired headphones or hands-free to answer calls;
Turn off the wifi connection when not using your phone; turn off wifi wireless devices, which reduces the source of non-ionizing radiation.
One thing that needs special attention is that the radiation intensity of mobile phones is related to the signal strength of mobile phones. If the communication signal is poor, the mobile phone must maintain high power to search for base stations to maintain communication, and the radiation from the mobile phone will be greater.
Try to make phone calls in an open outdoor environment. The communication signal is good and the mobile phone radiation is low.
During thunderstorms, when the communication signal is poor, try not to use your mobile phone. This not only reduces mobile phone radiation, but also prevents lightning strikes.
When driving at high speed, the mobile phone needs to constantly search and switch base stations to connect, which will increase the transmission power and generate more mobile phone radiation.
During mobile travel, such as on high-speed trains, trains, and elevators, try not to use your cell phone to reduce the power increase caused by switching base stations and also help reduce radiation.
When the mobile phone is connected to the Internet, especially when the mobile phone is dialed, the amount of radiation is the largest, which is equivalent to about 3 times of the standby state. It is best to wait 1 to 2 seconds after the mobile phone is connected before making a call.
Many people are concerned about whether they can make calls while charging their mobile phones? There is also a saying on the Internet that "when the battery of a mobile phone is only one bar, the radiation dose is tens of millions of times." Is this true?
The power of a mobile phone has nothing to do with the radiation intensity of the mobile phone. The signal strength is the decisive factor in the radiation intensity of the mobile phone, so this statement is a rumor. It is best not to make calls while the mobile phone is charging, mainly because doing so can appropriately extend the life of the mobile phone battery.
In recent years, there is another interesting research discovery about mobile phone radiation. The intensity of electromagnetic radiation when using a mobile phone to surf the Internet is less than the radiation intensity of text messages, and the radiation intensity of sending text messages is less than the radiation intensity of making phone calls. From this point of view, when the signal is good, the mobile phone uses the same time and distance, and using the network to connect is the best choice to reduce mobile phone radiation.
In addition, the radio frequency signals of mobile phones may interfere with certain electronic medical equipment and navigation systems, that is, electromagnetic interference. The use of mobile phones is generally prohibited on airplanes; people with pacemakers should also prevent problems caused by using mobile phones and try to hold the mobile phone on the other side of the body where the pacemaker is implanted.
Finally, when buying a mobile phone, you must also buy a device that meets national standards. "Copycat" mobile phones have not been tested for radiation SAR values, do not have network access licenses, and often do not meet radiation limits. Their radiation harm to the human body is unknown. Some anti-magnetic mobile phone stickers or anti-magnetic mobile phone cases on the market are mostly gimmicks by merchants, and they are not helpful at all in preventing mobile phone radiation.
