He concluded that highly penetrating rays were from the discharge tube. Machines produce x-rays by accelerating electrons to extremely high speeds and then crashing them into a piece of solid material called a target. There, the electrons rapidly slowed down because they collide with atoms in the target, and part of the energy is changed into x-rays. Dentists use them to find complications, cavities and impacted teeth. Soft body tissue are transparent to the waves.
Bones also block the rays.
X-rays are used in industry to inspect products made by various kinds of materials. X-ray machines are used in airports to check luggage etc. In Science x-rays are used to analyze the arrangement of atoms in many kinds of substances, particularly crystals. Archaeologists used X-rays to examine ancient objects covered by a crust of dirt. Dangers A danger associated with X-rays is the extremely high voltage that occurs.
