-de onda milimétrica - que no usan rayos X<br />
-de retrodispersión - que utilizan rayos X de baja intensidad. <br />

Y entiendo que ahora se retiran estos de &#34;retrodispersión&#34;, cosa que me parece genial. No me sentiría cómoda pasando por ese tipo de escáneres que no dejan apenas nada a la imaginación</p><p>&#187;&nbsp;autor: <strong>auroraboreal</strong></p>]]></description>

<br />
Aquí describen la tecnología: <a href="http://www.tsa.gov/research-center/x-ray-screening-technology-safety-reports" title="www.tsa.gov/research-center/x-ray-screening-technology-safety-reports" rel="nofollow">www.tsa.gov/research-center/x-ray-screening-technology-safety-reports</a><br />
<br />
En este párrafo queda claro que está destinado a personas:<br />
<br />
<sup>For radiation safety, TSA issues procurement specifications that require all manufacturers to comply with nationally-recognized safety standards to ensure the safety of all passengers – including special populations like children, the elderly, and pregnant women – and operators during equipment usage<br />
</sup><br />
Y lo mejor, hasta se permiten comparar la radiación que recibes con otros hechos:<br />
<br />
<sup><b>By the Numbers<br />
</b>One year of naturally occurring background radiation: 300 millirem<br />
Annual recommended limit to the public of radiation from man-made sources: 100 millirem<br />
Chest X-ray: 10 millirem<br />
Flight from New York to Los Angeles: 4 millirem<br />
One day of natural background: approximately 1 millirem<br />
Drinking three glasses of water a day for a year: 0.045 millirem<br />
One backscatter X-ray screening: approximately 0.005 millirem<br />
</sup><br />
<br />
Aquí especifican las medidas que se toman para proteger la privacidad: <a href="http://www.tsa.gov/ait-frequently-asked-questions" title="www.tsa.gov/ait-frequently-asked-questions" rel="nofollow">www.tsa.gov/ait-frequently-asked-questions</a><br />
<br />
<sup>For Backscatter technology: A remotely located officer views the image and does not see the passenger, and the officer assisting the passenger cannot view the image. The image cannot be stored, transmitted or printed, and is deleted immediately once viewed. Additionally, there is a privacy algorithm applied to blur the image.<br />
</sup><br />
<br />
Y además:<br />
<br />
<sup>A. Backscatter technology projects an ionizing X-ray beam over the <b>body </b>surface at high speed. The reflection, or “backscatter,” of the beam is detected, digitized and displayed on a monitor. Each <b>full body</b> scan produces less than 10 microREM of emission, the equivalent to the exposure each person receives in about 2 minutes of airplane flight at altitude. It produces an image that resembles a chalk-etching, and has a privacy filter applied to the entire body.<br />
</sup><br />
<br />
Está claro que existen otras tecnologías, pero ese nunca fue el debate.</p><p>&#187;&nbsp;autor: <strong>a1984</strong></p>]]></description>

Los rayos X se utilizan para objetos, nunca para personas: La dosis de radiacción no sería despreciable.</p><p>&#187;&nbsp;autor: <strong>--198199--</strong></p>]]></description>

La radiación que tú enlazas, de 1 mm, también se puede utilizar para hacer un escáner, incluso en 3D, cosa que los escáneres basados en rayos X no pueden hacer. La equivalencia en terahertzs al escáner de rayos X es <a href="http://en.wikipedia.org/wiki/Millimeter_wave_scanner" title="en.wikipedia.org/wiki/Millimeter_wave_scanner" rel="nofollow">en.wikipedia.org/wiki/Millimeter_wave_scanner</a> .<br />
<br />
Donde quiera que busque encuentro que hay escáneres corporales que funcionan gracias a la dispersión de los rayos X.</p><p>&#187;&nbsp;autor: <strong>a1984</strong></p>]]></description>

<a href="http://en.wikipedia.org/wiki/Backscatter_X-ray" title="en.wikipedia.org/wiki/Backscatter_X-ray" rel="nofollow">en.wikipedia.org/wiki/Backscatter_X-ray</a><br />
<br />
<sub><i>Backscatter X-ray is an advanced X-ray imaging technology. Traditional X-ray machines detect hard and soft materials by the variation in transmission through the target. In contrast, backscatter X-ray detects the radiation that reflects from the target. It has potential applications where less-destructive examination is required, and can be used if only one side of the target is available for examination.<br />
<br />
The technology is one of two types of whole body imaging technologies being used to perform full-body scans of airline passengers to detect hidden weapons, tools, liquids, narcotics, currency, and other contraband. A competing technology is millimeter wave scanner. These airport security machines are also referred to as &#34;body scanner&#34;, &#34;whole body imager (WBI)&#34;, and &#34;security scanner&#34;. Reports of official discontinuation at airports began circulating January 18th, 2013.[2]</i><br />
