What sort of objects give off x-rays?

* Medical imaging equipment: X-rays are used in a variety of medical imaging procedures, such as X-rays, computed tomography (CT) scans, and fluoroscopy. These machines produce X-rays by bombarding a metal target with high-energy electrons.

* Industrial radiography equipment: X-rays are also used in industrial radiography to inspect welds, castings, and other materials for defects. Industrial X-ray machines are similar to medical X-ray machines, but they are typically more powerful.

* Airport security scanners: Airport security scanners use X-rays to scan passengers and their belongings for dangerous objects. These scanners produce low-energy X-rays that are safe for people to walk through.

* Particle accelerators: Particle accelerators are devices that use electromagnetic fields to accelerate charged particles to very high energies. When charged particles are accelerated to high speeds, they produce X-rays. Particle accelerators are used in a variety of scientific research and industrial applications.

* Neutron stars and black holes: Neutron stars and black holes are extremely dense objects that produce X-rays as a result of their gravitational fields. Neutron stars are the collapsed cores of massive stars that have exploded as supernovae. Black holes are the collapsed cores of even more massive stars that have collapsed under their own gravity.

* The Sun and other stars: The Sun and other stars produce X-rays as a result of their coronal activity. The corona is the outermost layer of the Sun's atmosphere, and it is heated to extremely high temperatures by magnetic activity.
