Full-Body Scanners, Are They Necessary?

At many airports throughout the country, passengers are welcomed by trouble and long headaches due to long security lines. Many travelers complain about the list of rules they must obey and the way they seem to keep getting worse. The solution to government troubles and headaches is a whole body scanner. The government insists that these whole body scanners are faster than traditional metal detectors, they are easier to detect weapons and bombs and reduce pressure on long safety lines.

Does airport security violate passenger privacy? Is a full body scanner necessary? How about pat? Is personal concern about privacy and radiation exposure more than safety? Or are they the precautions that passengers need to cooperate? If you are the head of the TSA, how do you find the balance between these issues? Please join the discussion and tell me what you think.

Since the introduction of the whole body X-ray scanner at the airport in 2007, there were many concerns about the privacy of travelers. Individuals need to walk through rectangular machines shooting different wavelength images of the human body to detect metallic and nonmetallic objects being carried under the traveler's clothing. This screening technique is provided in two forms: millimeter wave technology (MM wave technology) or backscattered X-ray (similar to X-ray used by dentists). Terrorist attacks involving aircraft in the early 21st century increased, so all-machine scanners were introduced to the airport to increase safety and improve the quality of screening of objects such as weapons and explosives.

TSA is experimenting with a US $ 170,000 full body scanner using millimeter wave technology at about 20 airports in the United States. Essentially, these scanners present rough but identifiable images of passenger nude pictures to TSA filters in different rooms. At the moment, TSA is blurring the passenger's face, but the genitalia and chest are not blurred. The older backscattering technique revealed in 2003 actually reveals more details of the body and is very realistic, but it has not been used yet. Currently, the scanner is used instead of tapping the TSA randomly or in response to passengers triggering the metal detector multiple times. However, since this technology was first introduced in Phoenix Airport, Arizona in 2007, privacy advocates have opposed it. They believe this is a clear infringement of individual privacy.
