Do I need security check to take the subway? 1 Do I need security check when I take the subway?
According to the data of existing papers, the radiation dose received by a chest X-ray is about 0.9 millisieverts, and 65,438+0 millisieverts is equal to 65,438+0 millisieverts. In other words, doing10.8 million times to pick up the bag is only equivalent to receiving an ordinary X-ray chest X-ray.
After reading the above, everyone probably knows that it is really safe for pregnant women to pass the security check, and the radiation is almost negligible.
Precautions for pregnant women to pass security check
In fact, pregnant women are most worried about being exposed to X-rays when they go through security inspection, but pregnant women should not be exposed to such rays when they go through security inspection. Don't worry. What needs to be added here is that if the pregnant mother has been pregnant for more than 36 weeks, it is best to stay at home.
I repeat here that the internal rays of the security instrument are basically direct, and they are all sealed in the security instrument. There is still a little scattering of rays, but the lead curtain at the entrance and exit of the security instrument can basically block it, and the inner wall of the security instrument is thick with lead walls. As long as the lead curtain is not greatly lifted, no radiation can be detected around the security instrument. Only when it is out of date in Li Tong, will it be electrified instantly and produce rays.
It is safe for pregnant women to pass the security check by subway, so pregnant mothers don't have to be too nervous about whether there is a lot of radiation after the security check. In fact, radiation is ubiquitous in our daily life, such as mobile phones and computers. So pregnant women don't have to worry about security when they take the subway. What they should pay attention to is to avoid radiation moderately in daily life and not to indulge in playing mobile phones and computers.

The subway is not like a bus, but you can swipe your local bus card. Usually, you buy tickets at the ticket vending machine next to the elevator. Please bring your own coins and change. If you really don't understand, you can go to the manual counter to buy tickets.
You can enter the station after buying the ticket. First, pass the security check. Size packaging must be screened. After passing the security check, brush the ticket on the door, the door will open automatically and then enter quickly. Half of the subway is on the lower floor, so take the stairs.

There are subway station names, the last station name and the next station name on the subway door. Pay attention to the direction of coming and going, don't sit backwards. Go down first and then go up. Be careful not to be crowded.
6. There is a road map and train running status in the carriage. Pay attention to the station you are going to. Every time I go to the radio station, the broadcast will play automatically. Please don't get on and off in order when you arrive at the station.
How do you know the positive and negative directions by subway?
When you take the subway, you can tell the positive and negative directions according to the signs. Generally speaking, there is a sign on each platform, and there is an arrow on the horizontal line below each station to distinguish the direction.
Gray indicates that the car will not pass, and the color direction represents the next stop to go, and you can also identify the positive and negative directions to go. The subway has its own station in the direction to go, which is the positive direction, and vice versa.
If you can't read the signs, you can listen to the radio prompts, or subway staff or passers-by at this time.
It's convenient to take the subway, but you need to pay attention to these problems when you sit. If something falls into the track, don't jump off the platform and pick it up yourself. You should seek the help of the station staff, otherwise your personal safety will be greatly affected.

It's usually convenient and quick to buy it at the ticket vending machine. Select the starting point and destination first, and then flip a coin or paper money (usually 5 yuan, 10 yuan) to buy according to the payment amount.
If you don't know how to use the ticket vending machine, or happen to have no money, it doesn't matter. You can go to the ticket office to buy or change money.
You can also apply for a local bus card that supports subway card swiping. You can pass directly by swiping your card at the checkpoint. You just need to recharge the bus card regularly.
Do I need security check to take the subway? 3 Precautions for taking children by subway.
1, try to resist the train door and not let it close.
If your child unfortunately falls between the door and the screen door, you should quickly press the train door to prevent it from closing, so that the door can clamp your arm or leg. This is because the train will never start as long as the door is not closed. After the system failed to lock the door for three times, the driver needed to manually open and close the door again.
2. Pull the inner door handle outward.
If both the screen door and the door are closed, you can also pull the handle on the inside of the door outward. It takes at least five seconds from the time the train knows that the door is closed to the time it starts. If you keep calm, it is no problem to open the door. As long as a gap is opened, the train will stop urgently.
3. Press the platform emergency stop button.
If you don't get on the bus at this time, you should immediately press the emergency stop button on the platform post. Emergency stop buttons are generally located on the columns at both ends of the platform near the front and parking spaces. Remember not to confuse them with fire alarms.
4. Press the alarm button/emergency door opener in the carriage.
When you see a child caught between the door and the screen door, you should keep calm quickly and press the passenger alarm button or the emergency door latch in the car immediately. Buttons are usually located on both sides of the door. The passenger alarm button can directly call the driver to call the police, and the emergency door opener can trigger the emergency stop.
