When it comes to radiation, almost everyone is afraid of it, especially special groups such as pregnant women.
In recent years, there have also been many claims about radiation, such as:
- The subway security gate radiates a lot, pregnant women must not pass!
- Mobile phone radiation causes cancer.
- When sleeping, the mobile phone is placed at the head of the bed, the radiation is greater, and so on.
Are there any truth to these claims? And listen to the editor one by one~
The subway security gate radiates a lot, pregnant women must not pass?
First of all, let's take a "peace of mind pill" - the security gate and the hand-held security detector are safe.
They are magnetic field generators, which are often used to detect dangerous metal objects carried by the human body, such as guns, controlled knives, etc.
Its radiation type is the same as that of mobile phones and computers, which belongs to electromagnetic radiation. Compared with the ionizing radiation of X-rays, electromagnetic radiation is much less frequent and has a much smaller impact on people.
Compared with mobile phones and computers that have been in contact with them for a long time, the short-term and trace electromagnetic radiation that passes through the security gate is insignificant.
As for the "green security check channel" provided by the subway station for pregnant women, it is actually more out of concern for pregnant women to avoid them being collided.
In addition, the fact that pregnant women do not need to go through the security gate does not mean that they can be "exempted": the security inspector will conduct a visual inspection or touch the row with his bare hands.
Can mobile phone radiation cause cancer?
It is safe to say that mobile phones are radiated, which mainly come from signal receiving antennas and transmitting antennas.
Mobile phone radiation and microwaves, infrared, ultraviolet, visible light, X-rays emitted by X-ray machines, etc., are all electromagnetic radiation, also known as electromagnetic waves.
These radiations are essentially the same, but at different frequencies, wavelengths, and energies.
As for whether mobile phone radiation causes cancer, according to current research, there is no conclusive conclusion.
In 2012, the World Health Organization defined mobile phones as "probable carcinogens", which mentioned gliomas, so it is still used as evidence that mobile phone radiation causes cancer.
However, so far there is no clear evidence that there is an equivalence between mobile phones and the onset of glioma.
In addition, the so-called "possible carcinogen" means that it is possible, but it is inconclusive.
Let's say it's related, but it hasn't been confirmed in the population, and some research results are irrelevant; Let's say it has nothing to do, no one is absolutely sure of this.
In short, whether mobile phone radiation causes cancer is not completely conclusive. However, everyone should be wary of the increase in body temperature in parts of the human body (mainly near the ears in contact with mobile phones) caused by prolonged calls.
Mobile phones cause local heating up of the human body, similar to microwave heating food, which starts heating from the inside.
Answering the phone for a long time will not only cause the area near the ears to be hot, hot, sweaty, but also warm up inside the head. If the mobile phone causes the local temperature to rise by one degree, it will cause certain harm to the body.
Suggestion:
- If the call time is long, it is recommended to divide into 2~3 times;
- Whenever one side of the head or face feels hot and hot, you should immediately stop talking, then scrub with hot water and massage your palms to increase local blood circulation and promote normal tissue activity in this area;
- If you really can't interrupt the call, it is recommended to use a hands-free or headset.
When you sleep, put your phone next to your pillow, and the radiation is greater?
When the mobile phone is placed next to the pillow, there will be a certain radiation after all, but it does not have much effect. Because the power density radiated by the mobile phone is too small.
If you are really worried, you can turn off the computer before going to bed. Because the mobile phone radiation comes from the receiving antenna and the transmitting antenna, after shutting down, the antenna does not work, and there is no radiation.
However, the editor said in my heart, instead of worrying about the harm to the body of putting the mobile phone on the pillow before going to bed, it is better to think more about the threat to health of playing with the mobile phone before going to bed.
Playing with mobile phones before going to bed, brain nerve cells are easy to get excited and not easy to fall asleep, which will affect the quality of sleep.
If long-term sleep is not good and insufficient, it will not only reduce human immunity, but also lead to a series of physical discomforts, such as becoming ugly, stupid, easy to fatigue, depressed, injured sperm and eggs, inducing Alzheimer's disease, mental diseases, metabolic diseases, cancer, etc.
