Since the terrorist attack of September 11, 2001, many countries have realized the importance of this serious security problem and have begun to suppress terrorism and actively participate in anti-terrorism cooperation to strengthen national security . . Scientists have developed technologies and research into high-performance guarantees. Some fundamental safety equipment is used in airports to control hazardous materials among passengers. The full body scanner is a typical example used in airports for security inspections, and it shows the latest airport security technologies. It mainly uses X-rays or millimeter waves to scatter and reflect objects onto the body. After scanning, the information will be sent to a computer and “bare images” will be displayed on the screen (Eaton, 2009). Nonetheless, the use of full-body scanners has sparked much public debate. Its validity and technical effectiveness have been questioned: is it really effective and comprehensive, and whether the doses used with the body scanner violate human rights and harm human health? Additionally, is the data secure? The government cannot ignore these issues; it should investigate some of the negative effects of using the full body scanner and carefully consider whether the full body scanner should be used universally in all airports.Recently, the explosive was easily detected by a full body scanner of a terrorist attack on Christmas Day, and it completely foiled an attack on Detroit (Lekic, 2010). The benefits of full body scanning have once again been highlighted; thus, many countries want to purchase it for their airport security.
