| Ampere | A unit of electrical current. |
| Anode | The positive electrode in the x-ray tube. |
| Atom | The basic unit of an element |
| Bremsstrahlung radiation | electromagnetic radiation produced when a charged particle decelerates after deflecting off an atomic nucleus. |
| Cathode | The negative electrode in the x-ray tube |
| Central ray | the exact center of an X-ray beam used to aim at the middle of the anatomy being imaged |
| Contrast | is the visible difference between light and dark areas on a radiograph. |
| Control panel | the interface or console used to select and adjust exposure settings (like voltage and time) before taking an X-ray. |
| Density | overall darkness or blackness of an X-ray image. |
| Dental radiography | the process of taking X-ray images of the teeth and mouth. |
| Digital radiography | the process of taking X-rays using digital sensors instead of film. |
| Digital imaging | the process of creating, viewing, and saving X-ray pictures on a computer instead of using film. |
| Distortion | the change in the true size or shape of an object on an X-ray image. |
| Dose (of radiation) | amount of radiation energy absorbed by the body. |
| Dosimeter | a wearable device that measures a person's total exposure to radiation. |
| Electron | negatively charged particle that circles an atom's center. |
| Energy | the power or force used to produce X-rays. |
| Extension arm | the adjustable metal arm that holds and moves the X-ray machine head. |
| Genetic effects | radiation-caused DNA changes passed down to a person's children. |
| Image | the final visual picture produced on film or a computer screen by an X-ray. |
| Image receptor | the digital sensor or film that captures the X-ray beam to create the final picture. |
| Intensity | the total power or brightness of the X-ray beam. |
| Ion | an atom that has gained or lost an electron, giving it an electrical charge. |
| Ionization | the process where an atom gains or loses an electron, giving it an electrical charge. |
| Ionizing radiation | high-energy radiation that can remove electrons from atoms, creating charged particles. |
| Kilo voltage peak (kVp) | the maximum voltage applied to an X-ray tube, which determines the energy and penetrating power of the X-ray beam.This |
| Latent period | the time between being exposed to radiation and when the first visible signs of damage appear. |
| Lead apron | a heavy, protective jacket worn by patients to block radiation from reaching vital organs during an X-ray. |
| Magnification | the proportional enlargement of an object's size on an X-ray image compared to its actual size. |
| Master switch, indicator light, selector buttons, exposure button | The switches, lights, and buttons used to power the machine, choose settings, and shoot the X-ray. |
| Matter | anything that has mass and takes up physical space. |
| Milliampere (mA) | the electrical current setting that controls the amount or quantity of X-rays produced. |
| Penumbra | the blurry or fuzzy edge around the sharp center of an X-ray image. |
| Personal radiation monitoring badge | a wearable device that tracks the total amount of radiation a worker is exposed to over time. |
| Photon | a tiny packet or particle of light or X-ray energy. |
| Primary beam | the main, original path of X-rays coming straight out of the X-ray tube before hitting any object. |
| Primary radiation | the original, useful X-ray beam that comes straight out of the X-ray tube head. |
| Quality (of x-ray beam) | the energy, penetrating power, or strength of the X-ray beam. |
| Radiation | energy that travels through space or matter as waves or high-speed particles. |
| Radiography | the final image or picture produced on film or a computer by X-rays.This is for informational purposes o |
| Radiology | the medical field that uses X-rays and other imaging technologies to diagnose and treat diseases. |
| Scatter radiation | a form of secondary radiation that occurs when an X-ray beam deflects off a patient's tissue or another object, changing direction and spreading into the room. |
| Secondary radiation | new radiation created when the primary X-ray beam hits and interacts with matter, like a patient’s tissues. |
| Sensor | an electronic plate placed in the mouth to capture X-ray images on a computer instead of film. |
| Sharpness | the clarity and crisp detail of the lines and edges on an X-ray image. |
| Somatic effects | radiation-caused health damages that appear only in the person exposed, not in their future children. |
| Thyroid collar | a flexible lead shield worn around the neck to protect the thyroid gland from radiation during an X-ray. |
| Tubehead | the heavy, lead-lined metal housing that contains the X-ray tube and produces the X-ray beam. |
| Tungsten target | small plate inside the X-ray tube that electrons strike to produce X-rays. |
| X-radiation | a high-energy form of electromagnetic radiation that can penetrate solid objects to create images of the inside of the body. |
