The German scientist Wilhelm Roentgen, who lived between 1845 and 1923, discovered x-rays in 1895. The first X-ray was of Roentgen’s wife’s hand, complete with her wedding ring.
X-rays have many uses: scientists use them to examine the molecular structure of materials such as plastics, doctors and dentists use x-ray machines to look inside their patients’ bodies without using surgery and engineers make x-ray scans of airplanes to find cracks that could cause mechanical failure.
In addition, the Sun, stars, and other objects in space produce x-rays naturally. And finally, airports have x-ray scanners to check luggage for weapons and other dangerous objects.
