Since the terrorist attack on September 11, 2001 occurred, many countries have realized the importance of this serious security problem and have started to crack down on terrorism and are actively participating in anti-terrorism cooperation to strengthen security national. Scientists have developed technology and research for high-performance safeguards. Some critical safety equipment is used at airports to control hazardous materials among passengers. The full body scanner is a typical example used at airports for security inspections and showcases the latest airport security technology. It mainly uses X-rays or millimeter waves to scatter and reflect objects off the body. After scanning, the information will be sent to a computer and “naked images” will appear on the screen (Eaton, 2009). However, the use of full body scanners has caused a great public debate. Its validity and technical effectiveness have been questioned: whether it is really effective and comprehensive and whether dosing via full body scanner violates human rights and harms human health? Also, is the data safe? The government cannot ignore these questions; should investigate some of the negative effects of using the full body scanner and carefully decide whether the full body scanner should be used universally at all airports. Recently, the explosive was easily detected by a full body scan of a terrorist on Christmas Day, and completely foiled a direct attack on Detroit (Lekic, 2010). The benefits of the full body scanner have been highlighted again; therefore, many countries want to purchase it for airport security.
