Radiation is defined as:
A form of energy carried by waves or streams of particles.
A beam of energy that has the power to penetrate substances and record image shadows on photographic film.
A high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube.
A branch of medicine that deals with the use of x-rays.
A radiograph is defined as:
A beam of energy that has the power to penetrate substances and record image shadows on photographic film.
A picture on film produced by the passage of x-rays through an object or body. (like a photograph made with x-radiation)
