The balance in the middle of providing security against threats and protecting our freedom has been fired up again with the airport body scanner issues raised in the first part of this year. In this article, we take a look at the two types of body scanners that are regularly employed by security personnel.
Security versus personal privacy. Personal freedom versus safety. Which should win out in modern society? There are proponents of each side and they often change positions depending on the definite facts being discussed! As technology continually evolves, the subject is only going to grow more controversial and more heated. Airport body scanners are just the newest hot topic.
Airport Security
The millimeter wave scanner is deployed in the airports of many countries for the purpose of performing body scans on travelers. The gadget comes with two antennas that shoot an highly high frequency radio wave in the middle of the two. The passenger stands in the middle and will often turn a full circle. The waves penetrate clothing, but not the body or hard items which are reflected. The reflected waves then are used to create a 3D version of the passenger on which any incommunicable items will be revealed. It is somewhat similar to what you see when luggage is put straight through a scanner.
Backscatter scanners work in a similar manner. The dissimilarity is x-rays are shot into the body to create the image. This in an revising over the millimeter wave scanner in that it will also show organic materials in addition to the general body. On the downside, the image is only shown in two dimensions and the idea of bombarding the body with x-rays raises health issues. new studies have shown that the overuse of scanning in the healing community straight through the use of x-rays, Mris and Ct scans may be a health issue.
So, what do these scanners honestly show the security personnel? Well, the acknowledge is everything...and I mean everything. The images can hardly be called titillating, but there is no doubt that a tourist can have honestly no expectation of privacy when being scanned. Either community is ready to accept this level of government control is a quiz, for another article.
