After pregnancy, women should be particularly careful to avoid any adverse effects of radiation on the fetus in their abdomen. Some pregnant women need to go through security checks frequently. Does taking a train for security checks after pregnancy have any impact on the fetus?
1. Pregnant, taking a train for security check
Generally, security check devices have radiation. If you are pregnant, you can request a person to check, and the security inspector (of the same sex) can touch it with their hand. However, the strictness of security checks varies from place to place, and you may need to inquire on-site. If it is really not possible, it will not have any impact on the pregnant woman's photo after a few attempts.
2. Is security check harmful to pregnant women
Nuclear medicine experts told New Express reporters that the radiation from subway and airport security checks is very low for humans and not enough to cause radiation damage to the human body. Pregnant women passing through security screening machines will not have any impact on their unborn babies.
The subway security inspection machine, like the security inspection equipment at train stations, airports, and important departments' entrances and exits, includes security gates, handheld metal detectors, and item inspection X-ray machines. These are only metal detectors rather than X-ray devices. The X-ray machines used for machine inspection of items use X-ray lines to pass through objects to obtain X-ray images, which are processed by computers and displayed on computer screens to identify images and evaluate the safety of objects. The principle is similar to conducting a human X-ray examination in a hospital, but the X-ray dose is much lower than that of medical X-ray equipment, with a tube current of 0.4-1.2mA, while medical chest X-ray machines have a minimum of 50mA, which is 50 times higher
Although there is a certain dose of X-rays, humans are not exposed to them, so they will not come into contact with the radiation. "Professor Jiang Ningyi emphasized that during security checks, X-ray machines inspect luggage items, not people.
3. Can pregnant women apply for manual security check
Faced with radiation issues, I believe many pregnant mothers are quite worried, fearing that in case of an accident, the damage cannot be compensated for. So when entering places like subways, airports, train stations, etc. where everything has to go through security checks, can pregnant women apply for manual security checks instead of machine checks?
It is reported that the so-called manual security check means that there is no need to use handheld detectors to take photos, and female staff are arranged for manual inspection. If the pregnant woman's belly is already very obvious and can be recognized at a glance, it is possible to manually check without passing through the machine security door by verbally stating it during the flight security check.
Although pregnant women can undergo manual security checks, passing through the security checkpoint is also relatively safe. The security checkpoint and metal detector have passed strict inspections and meet safety standards. It achieves high resolution through digital signal processing of induced parasitic currents and homogenized magnetic fields. However, the thickness of the emitted magnetic field is very low, which is not harmful to pacemaker wearers, frail individuals, and pregnant women.
4. Precautions for pregnant women passing through security checks
In fact, the biggest concern for pregnant women passing through security checks is being exposed to X-rays. However, pregnant women passing through security gates should not be exposed to such radiation, so they can still rest assured. It should be noted that if the pregnant mother is over 36 weeks pregnant, it is still better to stay at home.
Just to add another sentence, the internal radiation of the security check device is basically direct, and all of it is sealed inside the security check device. There is still a very small amount of scattering in the radiation, but the lead curtains at the entrance and exit of the security check device can basically block it. In addition, all four walls inside the security check device are thick lead walls. As long as the lead curtains are not lifted up significantly, the radiation cannot be detected around the security check device. Only when luggage passes through, will it be instantly powered on and emit radiation.
Pregnant mothers don't need to worry too much about passing through security checks, but they should be prepared for radiation protection in their daily lives. Avoid excessive concentration of household appliances, avoid prolonged or simultaneous use of multiple office and household appliances, and pay attention to maintaining a safe distance between the human body and appliances. The farther the distance, the less susceptible to electromagnetic wave damage. Radiation resistant foods such as green tea, milk, seaweed, seaweed, animal liver, etc. can be consumed in combination with the diet.
After pregnancy, pregnant women need to check their luggage during security checks. This type of security check has a relatively small impact on pregnant women and generally does not have any adverse effects on the fetus. However, pregnant women must be particularly careful in their daily lives to avoid the effects of various radiation on the fetus, such as television, computers, etc.
