X-ray baggage scanner is not the same as medical X-ray equipment!
The security gate is mainly used to detect metals, and it relies on a weak electromagnetic field to work. The normal output voltage is very small, and it will not cause adverse effects on the human body, pregnant mothers, or fetuses.
However, the X-ray baggage security inspection device for checking items is ionizing radiation, and because it is to see through the item rather than the human body, the radiation dose is larger than that of the medical X-ray machine, but this refers to its interior, and most people are fine. Will get inside.
What we should pay attention to is that the door curtain in front of the X-ray baggage screening device is called a lead curtain, which is a protective device to prevent X-ray leakage. During the operation of the security checker, the luggage will constantly open the lead protective curtain, especially during peak hours when there are a lot of people, the protective curtain is basically in a half-open state. Often some people rush to take back their luggage and lift the door curtain of the security screening device, opening the lead curtain and exposing themselves to the danger of radiation.
Studies have shown that according to the basic standard of ionizing radiation protection and radiation source safety of 1μSv/h when the X-ray baggage screening device is operating normally and the shielding curtain is completely closed, the X-radiation dose rate within 5cm can still meet the safety standard, but When it is in normal operation and the shielding curtain is half-open, the X-radiation dose rate reaches more than 3 times the safety standard, and when the shielding curtain is fully opened, it reaches more than 9 times. Therefore, if pregnant mothers often go in and out of the subway, you still have to pay attention.
When going through the security check, it is best for pregnant mothers to stay away from the baggage screening machine as much as possible, and to go around as far as possible. Even if there is baggage to go through the security check, you must wait for all the items to come out of the conveyor belt before reaching for it. stay.
If you want to wear radiation protection suits to increase your defenses, most of the radiation protection suits for pregnant women are vest-type, which cannot completely wrap the body to isolate radiation, and it is designed to prevent non-ionizing radiation. The defense against ionizing radiation can only be a drop in the bucket, and it is better than nothing. In case the radiation enters the gap between the clothes, it will be reflected many times, which is far less reliable than being far away from the security inspection device!

In the same way, as long as you are not close to electrical appliances, there is basically not much radiation, so don't worry too much. For mobile phones, although there is no radiation hazard, it is always bad for the body to be a bower for a long time. It is recommended to go outside and exercise more when it is fine.
