Medical experts warn that the intensity of radiation generated by airport security scans is more than 20 times higher than scientists originally estimated. Whole body scans will significantly increase the risk of passengers suffering from skin cancer, especially to children.
The experimental results show that the radiation hazard generated by the scan is mainly concentrated on the skin, and the skin is the most sensitive part of the human body to radiation. David Bweer, director of the Columbia University Radiology Research Center, said that although this radiation intensity is "lower" for individual passengers, he still hopes that researchers will be able to conduct more experiments in order to find that the scans are for radiation. What impact will sensitive people have?
David Bweerle said that for children and passengers who are prone to genetic mutations, the body scan of the airport is more harmful, because these people are relatively weak in the ability to repair dna that is damaged by X-ray machine radiation. In every 20 individuals, 1 person is susceptible to genetic mutations. The experts further explained that the airport's security screening is most likely to cause skin cancer, skin cancer is a curable disease, and the susceptible population is middle-aged and elderly people aged 50 to 70 years old.
However, there are also some voices different from the study on the question of whether airport security scans are detrimental to health. All countries have issued relevant standards in the intensity of radiation waves, as long as they do not cause significant harm to human health within the allowable range. The airport security inspection department stated that the use of human body scanners has only been fully demonstrated before implementation, and that the entire scanning process is very short-lived, so it is basically safe for the human body.
According to Dr. James Slall, director of radiology at the American College of Radiology and the Massachusetts General Hospital, the radiation generated at airport security is very weak, as long as it is not frequently exposed, it will not significantly affect human health. Slar said in an interview: “Our concerns about medical x-rays do not apply to these devices at all. The x-rays of these devices are very weak. The x-rays used for medical imaging must be very strong to penetrate the human body. The X-rays at the airport backscatter scanner were weak and reflected on the skin.†And the data disclosed on the website of the US TSA showed that the amount of radiation received by a full-body scanner is only equivalent to flying. The amount of radiation affected by flying for two minutes.
In addition, there are concerns that such body scan security screening methods compromise health and privacy. Some other experts believe that the large-scale use of such security inspection equipment may not be able to effectively improve airport security.

The ABS Magnetic Ring is used to inspect the "magnet lines" on the ABS encoder ring part of bearing that are connected to ABS (anti-lock brake) systems.
A magnetic ring is fixed to the rotating hub at the rear and a closely spaced wheel speed sensor picks up magnetic flux changes to produce pulses processed by the ABS controller.
