In fact, these concerns are too much to worry about. According to Air China's regulations, pregnant women who are more than 35 weeks pregnant or whose due date is within 4 weeks cannot get on the plane, mainly because of the fear of premature birth and the lack of appropriate medical equipment on the plane. But the airline does not stipulate that pregnant women in the early stages of pregnancy can not be normal security checks on the plane.
The security equipment is divided into two categories, the baggage lane and the passenger lane. The former through the X-ray fluoroscopy, the items in the luggage in the form of images displayed on the computer screen, X-rays are harmful to the body, so the equipment on both sides of the lead plate isolation, to avoid harmful radiation to the human body.
And the latter, including security gates and handheld metal detectors, they are detected by magnetic lines of force, which cannot penetrate metallic substances, and the alarm will go off if a passenger is carrying a metal object through the security gate. Metal detector and handheld metal detectors and object inspection X-ray machine, these only belong to the metal detector rather than X-ray device, the object for the inspection of X-ray security machine is the use of X-rays through the object and X-image, through the computer processing is displayed on the computer screen, to identify the image, to assess the safety of the object.
"The principle is similar to that of a hospital X-ray examination of the human body, but the X dose is much lower than that of a medical X-ray device, but the human being does not pass through the machine, and therefore does not come into contact with the rays." The X-ray machine checks luggage items, not people. According to China's "ionizing radiation protection and radiation source safety basic standards" to calculate, a person standing in the entrance of the security machine about 10CM 52 days without moving to reach this amount, the amount of radiation is not enough to cause radiation damage to the human body, including pregnant women through the security machine will not have an impact on the baby in the abdomen. Therefore, the majority of travelers can rest assured that they will be inspected when they pass through the security checkpoints.
In fact, the metal detector and handheld metal detectors are in line with the main safety standards and passenger safety standards, it is through the induction of parasitic currents and homogenization of the magnetic field of the digital signal processing method to obtain high resolution, to emit a magnetic field thickness is very low, on the cardiac pacemaker wearer, pregnant women, frail people, magnetic media and other electronic devices are harmless.
So now you don't have to worry about this problem anymore! Wisdom security wishing moms a happy family, baby healthy and healthy.
