In recent days, security incidents have occurred frequently. Many subway stations in Guangzhou have installed security inspection machines. Many expectant mothers are worried: Will passing the security check for pregnant women affect the fetus? Will radiation during security checks affect the fetus? Here, the editor wants to tell you that the radiation during security check has little impact on the fetus.
How much safe radiation is there?
Subway security inspection machines are the same as the import and export security inspection equipment at railway stations, airports and important departments. It is a device that detects objects.
Simply put, it uses the principle of imaging when X-rays pass through an object, processes the image through a computer, and displays a recognizable image on the computer screen to evaluate the safety of the object.
In fact, this is similar to doing an X-ray on the human body in a hospital. The difference is that the X-ray dose of the security inspection machine is much lower than that of the medical X-ray equipment, while the radiation dose of the medical chest X-ray machine is at least 50 times that of the security inspection machine.
According to the manufacturer, the internal radiation of security inspection equipment is basically direct, and all of it is sealed inside the security inspection equipment. There is still a small amount of radiation scattering, but the lead curtains at the entrance and exit of the security detector can basically block it. In addition, the four walls inside the security detector are thick lead walls. radiation-free. Only when the baggage passes does it become instantly energized and produce radiation.
In this case, will safe radiation cause harm to the fetus?
Pregnant women going through security checks will affect their fetuses
Security inspection equipment is divided into two categories: baggage channel and passenger channel. The former uses X-ray fluoroscopy to display the items in the luggage on the computer screen in the form of images. X-rays are harmful to the body. Therefore, there are lead plates on both sides of the device to avoid harmful radiation to the human body. The latter include security gates and handheld metal detectors, which detect through magnetic lines and cannot penetrate metal objects. If a passenger carries a metal object, an alarm will sound when passing through the security gate. However, magnetic lines are almost harmless to the human body and meet safety standards, so passengers can rest assured. Does security check threaten fetal health? Obstetricians and gynecologists also denied this claim. From the perspective of a gynecologist, so far there are no medical reports on the adverse effects of security checks on pregnant women and fetuses. In addition, some common radiation in life, such as computer radiation, microwave radiation, etc., have minimal impact on pregnant women and fetuses, so there is no need to worry.
Does the security check for pregnant women have any impact on the fetus? Through the above introduction, does the expectant mother feel at ease?
