Date Critical Essay: Are Airport Security Scanners Safe In an article published in the PHYS.ORG on March 16, 2011 entitled “New articles examine safety of airport security scanners” the news report examined previous discourses written by David J…
This article proffered the most balanced information on the safety of airport security scanners given that arguments on the potential radiation-induced cancer risks have been appropriately discussed using Brenner and Schauer’s contentions. The aim of the current essay is to provide a critical analysis of the online materials found on the subject of security scanners as prescribed by the Transportation Security Administration (TSA) that there is a need to “use whole-body imaging scanners as a primary screening measure on travelers passing through airport security checkpoints” (Radiological Society of North America par. 1). In this regard, the mentioned news articles written by both Brenner and Schauer were aptly summarized with relevant issues emphasized to shed light on the subject. According to the article, there are currently two types of scanners used in airports to screen various travellers. The first type is the scanner that “employs millimeter wave technology, which delivers no ionizing radiation” (Radiological Society of North America par. 1). The other type is the scanner that “uses backscatter X-rays that expose the individual being screened to very low levels of ionizing radiation” (Radiological Society of North America par. 1). ...
hreshold" (LNT) risk model, which says that the smallest dose of low-level ionizing radiation has the potential to cause an increase in health risks to humans” (ScienceDaily par. 5). This article confirmed the risks involved in low levels of ionizing radiation, however, since it was published in 2005, the reliability and applicability could be diminished. The article being reviewed was actually effective in providing a balanced discourse by first presenting the arguments of Brenner, to wit: “given that up to one billion such scans per year are now possible in the U.S, we should have concerns about the long-term consequences of an extremely large number of people being exposed to a potential radiation-induced cancer risk, no matter how slight” (Radiological Society of North America par. 2). On the contrary, Schauer asserted that “critics of security screening acknowledge that doses from backscatter X-ray systems are very low and safe for an individual” (Radiological Society of North America par. 5). However, it is commendable that the discourse acknowledged that both radiological experts agree that “the scanners using millimeter wave technology should be considered as a first option, since they are similar in cost and functionality to the backscatter machines, but do not expose the passenger to ionizing radiation” (Radiological Society of North America par. 8). The information and the statements issued by these professionals indicate that there are still eminent risks of being exposed to the backscatter machines despite the published announcement that the risks are very minimal. The supporting report from other websites and scientific organizations confirm that there are still risks involved despite the apparent very low dozes that humans could be exposed. ...

This limitation is acknowledged in some countries. There are individuals who underwent rigorous and special training which would give them the ‘license’ or the capability to engage passengers in a conversation to detect threats instead of merely relying on equipment to do the job (GAO, 2004).
America had to do something to prevent any other attack. Check-in procedures are more elaborate and are take more time. Some people find these measures unnecessarily too strict. This opinion prompts one to think on whether the security check is too tight.
Multiple methods were used with limited success to stop weapons from being carried on. The question that many fliers are asking is if the new technology is in fact healthy, and if it is not then is there anyway to go around the requirement. Thousands of hours of research has been done that both proves and disproves that this technology is in fact safe, and can decrease the chance of another terrorist attack effectively and efficiently.
Prior to the terrorist attack, the government’s policies only allowed for a substandard level of airport security. The problem not only focused on private security firms, but the dependence on airline financing, as well as inadequate oversight on the part of the Federal Aviation Administration (FAA) and other stakeholders in the fragmented airport security domain.
The research focuses on determining whether to replace the government’s airport screeners as well as passenger screening personnel with private persons. The safety and security of the passengers, crew, and airplanes far outweigh the
But the question raised is whether this machine can detect explosives hidden in private areas. Other areas of concern are the comparatively less speed of WBI, the fact that people with medical concerns are ineligible for such concerns, health concerns as images are
The essay, therefore, contained strengths in providing balanced information from the assertions made by both Brenner and Schauer. Likewise, one noted that the article also appropriately provided the accurate links to the discourses written by both Brenner and Schauer sourced from the monthly journal, Radiology.
