Primary radiation is defined as

Explanation:
Primary radiation is the X-ray beam produced in the dental X-ray tube head and directed toward the patient and image receptor; it is the useful, intended beam that forms the radiographic image. It is emitted before any interaction with matter. The other statements describe radiation that occurs after the beam interacts with the body (secondary radiation), or radiation from radioactive materials (which is not used in standard dental radiography). Hence, X-rays coming from the tube head define primary radiation.
