Did you know about the radiation
♪ ♪ i'm not sure ♪
Today, mobile phones are inextricably linked to our lives and work, and while access to modern communication technologies and the era of electronic information has been greatly facilitated, mobile phone radiation health has continued to receive attention。
Scholars have carried out a series of studies to answer questions about whether, and how, mobile radiation harms the body and how to avoid harm。
Let's do a little test, see what you know about mobile radiation

The correct answer is at the end of the text
It's a cancer killer
Cellular radiation is non-ionizing, and the energy of the wave is low enough to cause cancer in an ionizing impaired cell, but it affects its functioning。
According to the international committee for the protection of non-ionizing radiation (icnirp), local exposure doses to humans exceed the limit, causing functional disorders in humans and sleep disorders resulting from the disruption of the physical electrical activity of the human brain, resulting in loss of vision, cataracts, etc。
Apple also tested the electromagnetic wave absorption ratio of mobile phones at a distance of 5 mm from the body, showing that its radiation levels exceeded the ceiling set by the united states federal communications commission (fcc) for mobile phone safety. Imagine, when your mobile phone is close to you, you get more radiation。
Although the increase in the incidence of brain gelatinoma among mobile phone users remains controversial, on 31 may 2011, the international agency for research on cancer (iarc) officially listed cellular radiation as a potential carcinogen。
The effects of cellular radiation on reproductive health are also of interest to the scientific community. Clinical epidemiology and experiments have confirmed that mobile phone electromagnetic radiation has adverse effects on reproductive function, causing abnormal morphological structure and damage to cells, but also results of negative studies. It is recommended that mobile phones should be placed as far as possible away from the groin in everyday life, especially for men and women of reproductive age。
Influences on health, children are more likely to be “injured”
Children are more vulnerable to electromagnetic radiation than adults. The brain is the main exposed organ of cellular radiation. According to experts, the nervous system was not fully developed during childhood and even low-frequency electromagnetic radiation could interfere with the active electrophysiological activity of children, resulting in neuron damage。
The longer children and adolescents use mobile phones, the more electromagnetic radiation they will be exposed to, the greater the risk of physical damage。
An expected group study of 234 young people found that one year later, through the cognitive testing system, the longer they use wireless devices, the greater the amount of electromagnetic radiation they experience and the greater the loss of memory。
However, who (world health organization) considers that the results of these studies on the memory, learning and cognitive functions of mobile phone radiation are inconsistent; the most consistent health risks associated with mobile phone use are distraction driving and vehicle accidents。
Reduce the radiation from your cell phone
It is almost impossible not to use a mobile phone, but scientific use can reduce the radiation damage of a mobile phone and, in addition to minimizing the frequency and duration of its use, the following can be noted:
Avoid close placement of mobile phones
Do not leave a cell phone on the bedside while sleeping
To the extent possible, wired headphones or off-line telephones
Wifi connections are closed when mobile phones are not used; the closure of the wifi wireless device reduces non-ionizing radiation sources。
One point that needs special attention is that the radiation intensity of mobile phones is related to the signal strength of mobile phones. Communications are poor and mobile phones are expected to maintain high power to search for base stations to maintain communications, with greater radiation。
Call as much as possible in the outer space environment, with good communication signals and low radiation from mobile phones。
During thunderstorms, communication signals are poor and mobile phones are kept as low as possible, reducing both cellular radiation and lightning-proof。
While travelling at high speed, mobile phone connections require constant search and switching of base stations, which can add additional launch power and generate higher levels of cellular radiation。
As far as possible, mobile phones are not used in moving processes, such as heavy iron, vehicles and elevators, reducing the power gain from switching to base stations and reducing radiation。
Cell phones are the most rapidly irradiated on the internet, especially when they are dialed, which is about three times as high as on-board, preferably by talking to one to two seconds after they are connected。
A lot of people care if they can call when they charge their phones? Is that true
Cellular power is not related to the radiation intensity of the mobile phone, which is a determining factor in the radiation intensity of the mobile phone, and this is a rumour. It would be preferable not to make phone calls when charged, mainly because this would appropriately extend the life of cell phones。
There has been an interesting study of mobile radiation in recent years. Electromagnetic radiation using mobile phones on the internet is less intense than that of text messages, and that of text messages is less than that of telephone calls. Thus, when signals are good, mobile phones are used at the same time and at the same distance, and internet connections are the best option to reduce mobile radiation。
In addition, radio frequency signals from mobile phones may interfere with certain electronic medical equipment and navigation systems, i. E. Electromagnetic interference. The use of mobile phones is usually prohibited on the aircraft; people who wear pacemakers are also required to prevent problems from using them and to hold them as far as possible on the other side of the implant。
Finally, mobile phones are selected, and equipment that meets national standards must also be purchased. The mobile phones of the shan edition do not perform radiation sar tests, do not have internet access permits, and radiation limits are often not up to standard, and they do not know about radiation damage to humans. There are mobile phone anti-magnetic stickers or anti-magnetic phone casings on the market, which are mostly the work of merchants and which do not help to protect against mobile radiation。
