In the past screening were more focused on passengers entering the lounges and so on with detectors specified to detect metallic objects and x-ray machines used to scan the items for carry-on purposes (Elias, 2010). After the terrorist attacks taking place from time to time and after the recent attack in the Russian airport there has been a growing need to improve security. The Transportation Security Administration (TSA) under the U.S Department of Homeland Security has had to face a number of barriers in order to make their screening process more efficient. Airport traffic has been on the increase for a long time and screening processes make it cumbersome for the passengers. There also needs to be a balance between the needs of the passengers and the security. Scares continue to take place even now as with the happening on 25th December 2009 when a Nigerian man attempted to ignite an explosive device while on board a plane heading to Detroit (O’Connor amp. Schmitt, 2009). Airports across the world are looking towards new technology to help security staff catch suspicious people and detect object deemed illegal on flights now. The problems that arise out of these technological advancements in airports are many such as privacy concerns, health concerns and subjection of minors to the scanning. On the other hand, such technology can prove helpful in foiling terrorist plans, so there needs to be a weighing of the harms and benefits.Imaging technology has been bought and installed in the various airports all across the United States. According to the TSA, there are two types of imaging technology that is being used, the millimeter wave and the backscatter x-ray. As of now, according to the TSA, there are 486 of these imaging devices that are being used across 78 airports in the United States (Transportation Security Administration).
