Recently, the issue of "iPhone 12 radiation exceeding the standard" has sparked global discussions, and it is reported that multiple countries have taken action.

The French National Frequency Agency (ANFR) stated that they tested 141 mobile phones and found that the SAR value of the iPhone 12 exceeded 40% of the legal limit. They have requested Apple to remove the iPhone 12 from the French market. (Note: SAR value represents the impact of radiation on the human body. The lower the SAR value, the less radiation is absorbed.)

South Korea has also requested Apple to submit a report on the radiation issue of the iPhone 12, and European countries such as Belgium, Germany, and Italy are tracking France's regulatory actions against the iPhone 12.

Is there a problem with the iPhone 12 sold in China? A communication industry professional said, "Our country's SAR standard is consistent with the French SAR standard. In theory, if it exceeds the standard in France, it also exceeds the standard in China. We should also test it

As soon as the news came out, many netizens trembled with their phones: What should we do? I have been using iPhone 12 for 3 years, can my body still be saved?

Fancy radiation protection, young people have started again

As soon as she saw the news of "iPhone12 radiation exceeding the standard", Jiaxin immediately opened her mobile phone Taobao and ordered a "radiation protection film" and a pair of "radiation protection glasses" for her phone.

She started using iPhone 12 three years ago because she was always worried about the radiation problem of electronic products, so she never dared to play with her phone while charging, nor did she dare to make calls when the signal was poor. This year's physical examination for employment showed that all indicators were relatively normal, and she was secretly pleased.

When it comes to radiation protection, she is very knowledgeable. When she was a child watching TV, her parents asked her to stay 4 to 5 meters away, saying she was afraid of radiation, which made her aware of radiation prevention from a young age.

As she grew up, Jiaxin became a "radiation fearing star", with various green plants scattered around her workstation computer; Use the microwave, press the start button and leave first, then wait for the heating to complete before taking the food; Using a hair dryer to blow your hair while maintaining a distance of 15 centimeters

Be careful and cautious in every aspect of life, but Jiaxin never expected that her beloved phone, which she accompanies day and night, would now have the real hammer of "radiation exceeding the standard". So, immediately applying a "radiation protection film" and putting on a pair of "radiation protection glasses" became her last stubbornness.

Xiaowei is also a "radiation protection expert". Her job requires her to face the computer all day long, and planting green plants can no longer meet the needs of radiation protection. So she put on a large "radiation protection mask", covering from the corners of her eyes to her neck, and then put on a duckbill cap to cover her forehead, trying her best to minimize the damage of radiation to every inch of her skin.

And the delicate boy Aqiang started researching dietary therapy to "treat" radiation. Carrots, watermelons, oranges, broccoli, olive oil, red grapefruit, and other foods are all his anti radiation dietary heroes. Nutrients such as cod liver oil, vitamin E, and vitamin B are also present every day. It can resist radiation and protect vision, in short, it's not harmful to eat it... "Aqiang said seriously.

Even if they haven't fought against radiation like the above three, I believe many people have made efforts to prevent mobile phone radiation in their daily lives: setting their phones to airplane mode while sleeping; Mobile phones should not be placed at the bedside; Try not to stick your head on the phone and keep it away when making calls Is it really that scary that everyone is "talking about radiation and turning pale"?

What are the hazards of mobile phone radiation?

Radiation, commonly known as electromagnetic waves, is ubiquitous in daily life and can be divided into ionizing radiation and non ionizing radiation.

Ionizing radiation refers to radiation energy that is high enough to ionize atoms, and when it reaches a certain amount, it can directly break the chemical bonds of biomolecules, which may cause damage to human cells. X-rays, CT scans, and nuclear medicine examinations all produce ionizing radiation.

Even bananas and potatoes emit ionizing radiation. Bananas are rich in potassium, with approximately 0.0117% of natural potassium being radioactive potassium. For every banana eaten, one is exposed to approximately 0.0001mSv of radiation.

When we take high-speed trains or subways and pass through security check instruments that emit X-ray ionizing radiation, we are also exposed to ionizing radiation, but in very small amounts.

A paper in "Radiation Health in China" states that if a person passes through a security checkpoint twice a day on average throughout the year, taking 20 seconds each time, the total amount of radiation received throughout the year is 1/14000 of 1mSv, which is less than the amount consumed by eating a banana.

Instead of ionizing radiation, it cannot ionize atoms, resulting in lower energy and less damage to the human body. The electromagnetic radiation generated by mobile phones, computers, televisions, microwave ovens, flashlights, etc. that we often come into contact with belongs to non ionizing radiation.

When we make phone calls with our mobile phones, the radio waves sent to the base station are absorbed by our bodies to some extent, forming mobile phone radiation. However, compared to the frequency of ionizing radiation such as X-rays, the radiation frequency of mobile phones is very low.

The "Knowledge Base on Common Issues of Radio Interference in Satellite TV Reception Signals" released by the Ministry of Industry and Information Technology points out that although electromagnetic radiation is everywhere and always present, it is only called electromagnetic pollution when it exceeds a certain intensity (i.e. safety and health standard limit), which will have negative effects on the human body and even induce certain diseases.

Studies have shown that the average annual effective dose of natural radiation received by each person in the world is 2.4mSv, and to achieve a high risk of cancer, the minimum annual radiation dose is 100mSv; To achieve radiation lethality, it is necessary to receive a large amount of radiation dose (7000-1mSv) in a short period of time.

Although mobile phones are good, their applications are moderate

Although there is no need to panic too much about the radiation problem of mobile phones, long-term use of mobile phones can indeed have a certain impact on our bodies.

President Shi Yigong and his team of Xihu University conducted in-depth research on the effects of radio frequency electromagnetic radiation (RF EMR) on specific cells in the brain. Animal experiments showed that prolonged exposure to 2.4GHz electromagnetic radiation released by common wireless electronic devices reduced non rapid eye movement sleep and rapid eye movement sleep time, and correspondingly increased wakefulness time.

It can be seen that long-term exposure to electromagnetic radiation in wireless range can indeed cause specific physiological reactions in organisms, such as affecting sleep structure.

In addition, studies have shown that excessive use of mobile phones can lead to a range of health symptoms, such as headaches, impaired attention and memory, fatigue, irritability, anxiety, insomnia, back pain, neck pain, eye fatigue, etc.

A study published in the journal Neurology shows that the use of smart phones can increase the incidence rate of headache.

For many young people, problems such as headaches, insomnia, and endocrine disorders are common, but it is difficult for anyone to say whether this is due to radiation from their phones or staying up late to use their phones or play games.

Today's young people are accustomed to "risking their lives while saving themselves", overly relying on mobile phones and fearing that they may emit radiation. The fancy radiation protection method may only have a greater effect as a psychological comfort.

At present, there is no authoritative data indicating how far away a mobile phone is from the head, but the radiation of a mobile phone decreases with distance. Some studies suggest that 50 centimeters is a safe distance, while others say it is 1.5 meters. After all, when the mobile phone is 1.5 meters away from the body, it can at least ensure that you can sleep comfortably without touching the phone.
