The United States military, law enforcement, and border patrol can now get their hands on a newly developed x-ray gun capable of scanning inside of different materials using backscatter technology. The United States military, law enforcement, and border patrol can now get their hands on a newly developed x-ray gun capable of scanning inside of different materials using backscatter technology. The scanner, called the Mini Z is manufactured by American Science and Engineering, who says their product offers "fast, portable, real-time detection of hidden organic threats, such as drugs, contraband, plastic guns, ceramic knives, and explosives." Although the strip search x-ray machines used in airports were removed because of concerns about privacy, the handheld device employs the same technology. In the near future, the x-ray guns might be used to see what's inside of people's bags at public events and travel checkpoints.It is more efficient than the x-ray machines used at airports, requiring only 10 watts to function compared to larger devices that use up to 3 thousand watts. And each Mini Z reportedly costs around 50 thousand dollars, which is half the price of airport scanners. The next step for American Science and Engineering is to create x-ray glasses, but the x-ray tubes need to be smaller than the ones used in the Mini Z, and that technology is still in development.
