However, Teacher Alin reminded that because the standard of radiation protection suits is still not perfect, many people will wrap their hands after buying radiation protection suits, and the near-field radiation harmful to human body is the electromagnetic wave emitted by the mobile phone itself. In fact, it is unscientific to detect the shielding effect of electromagnetic wave emitted by mobile phone signal base station. This has also made many businesses take advantage of it. Many people think that since electromagnetic shielding clothing is used to shield electromagnetic waves, it can shield mobile phone signals, and the shielding effect is definitely poor. This view is not entirely correct. Electromagnetic waves have both near-field radiation and far-field radiation. Mainly based on the wavelength radius of electromagnetic waves, the region is far-field radiation. The human body and the mobile phone are basically in close contact, receiving near-field radiation, which is the most harmful. The distance between the human body and the mobile phone base station is generally more than 20 meters, so it receives far-field radiation, and the radiation intensity meets the national standards, which is basically harmless to the body. However, shielding the cell phone signal is only shielding the far-field radiation emitted by the cell phone base station, which is of little significance.
Warm reminder: buy regular brands, use scientific methods to detect, and actively stay away from radiation sources in your life. Such as mobile phones, computers and so on.
In the choice of radiation protection clothing, we can start from the following three points.
A, it depends on the nature of pregnant women's work and the surrounding radiation environment. If the surrounding radiation is very strong, it is recommended to choose a radiation-proof vest, which has the strongest protection for yourself and the fetus in the abdomen; If the surrounding radiation is very weak (such as not touching computers and rarely touching other electrical appliances), you can choose a radiation-proof Chinese bra.
B, even if the radiation source around pregnant women is very weak, it is recommended to choose a radiation-proof vest for more than three months, which can better protect the health of the fetus.
C, return guarantee. That's the point. The quality of brands that dare to make a promise of return and exchange will naturally not be too bad, and expectant mothers must pay attention.
