What is an X -ray backscatter?
Backscatter X -ray X -ray is an advanced form of traditional X -ray scanning. It differs from traditional double energy systems by providing a much more complex image, especially organic material. Some controversies surround the use of X -ray scanners as security measures, both for privacy and for fear of radiation exposure.
traditional X -ray rays create a picture by measuring the amount of X -rays absorbed by an object undergoing detection. In medical use, the reason is why the bones are easier to see on the X -ray than the skin or organs, that the bone composition absorbs more X -rays. On the other hand, the X -ray technology detects the reflection of the radiation from the examined object.
low -scale elements such as hydrogen or carbon, X -ray photons distract rather than absorb, which is much less visible in traditional X -rays. Most soft tissues in the body isIt consists of these low -based weighing elements that make X -rays are relatively unnecessary for examining organic material. Back dispersion machines are considered much better than traditional X -rays to explore soft tissue, because the reflection of the created tissue is much more detailed than the image given by the absorption methods. Although medical facilities, although primarily rely on computer tomography or display magnetic resonance imaging for the examination of poor X -ray areas, Backscatter has gained popularity in security persecution.
The most important use of X -ray machines Backscatter is at commercial airports. These machines can introduce for the detection of hidden weapons or explosives and can create a highly detailed two -dimensional picture of anyone who goes through the scanner. The disadvantage of this procedure is that the created image is quite clear and removes hiding allThe clothing and actually creates a naked picture of the target. This has led to the consistency of the explosion among civil freedom activists, religious leaders and many people uncomfortable with the idea of naked image of acquiring and viewing others, especially because scanners have the ability to store and store pictures. In November 2010, over 100 backscatter X -ray images were leaked to the Internet.
Some people have also raised concerns about the radiation exposure caused by X -ray -backing radiation machines. When accepting traditional X -ray in a medical facility, people usually have a cover of aprons that protect them from radiation. It seems that most experts agree that back scatter scanners represent a small danger, even for frequent leaflets. According to some healthcare professionals, the person would have to undergo hundreds of X -rays per week to be in the risk of radiation.
