Critical : Are Airport Security Scanners Safe

Download file to see previous pages... 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. ...Download file to see next pagesRead More
