What is primary radiation?

Primary radiation is the penetrating x-ray beam generated at the anode target in the x-ray tube and exiting the tubehead toward the patient. It is the unmodified radiation produced directly by electrons hitting the tungsten target, with its energy controlled by kilovoltage and its quantity by milliamperage. This beam remains primary until it interacts with matter. When it does interact with tissues, secondary radiation such as scattered photons or characteristic radiation arises, but those are produced after the primary beam has encountered matter. The other statements describe radiation that results from interactions, not the initial beam produced at the target.
