The body escánares at airports have been one of the most controversial decisions in aviation safety in recent years. A study by the University of Arizona is adding fuel to the fire and ensuring that more deaths may occur due to radiation, a terrorist attack. Scientists at the University of Arizona have claimed that the probability of dying from the radiation of a whole body scan and a terrorist attack are the same: one in 30 million. Experts say that the beam emitted by the free scanner radio is low and offers a small dose of radiation in the body but because the beam is concentrated in the skin, one of the most sensitive organs to radiation from the human body, dose may be 20 times higher than previously estimated. Even more worrying radiation machines when they are damaged when they are in operation as "a failure in the device could increase the dose of radiation," says one of the scientists involved in the study, Peter Rez. Perez, along with the rest of scientists has studied the radiation dose from the scans using the images produced by them and says not really "there are arguments to continue incorporating these types of machines in airports. " Such devices create an image of the entire body is connected to a computer in a private room. Collect all the natural curves of the human body to detect whether the passenger is in possession of weapons or drugs at the time of boarding. . . Designed by the authors of CCleaner (a reference in his register, so to speak), Recuva is a free scanner radio utility that allows you to restore files accidentally deleted from your computer. This version is portable on a USB stick or other removable media. This concerns both files emptied from Recycle Bin the images and other files accidentally deleted from the memory card from your camera, or even the elements of your MP3 player. Recuva also restores deleted files in bugs, crashes and other virus attacks. Clicking on the button "Recover", and that's it. Little more, during the scan of your disk, the program informs you of the status of files and whether the clusters have been rewritten. .
