Dental Radiology Exam Study Guide
with Complete Solutions

Discovered x-ray in 1895 - Answer✔️✔️-Wilhelm Roentgen

Production of ions - Answer✔️✔️-Ionization

Atom that gains or loses electron and becomes electrically unbalanced -
Answer✔️✔️-Ion

When electron is removed from

An atom in ionization process - Answer✔️✔️-Ion pair results

Ion pair - Answer✔️✔️-1. Atom becomes positive ion

2. Ejected electron becomes negative ion

Radiation that is capable of producing ions by removing or adding an
electron to an atom - Answer✔️✔️-Ionizing radiation

X-rays produce? - Answer✔️✔️-Ionization

Tiny particles of matter that possess mass and travel in straight lines at
high speeds - Answer✔️✔️-Particulate radiation

Particulate radiation - Answer✔️✔️-1. Electrons

2. Beta particles

3. Cathode rays

4. Alpha particles

5. Neutrons

6. Protons

Propagation of wave-like energy (without mass, without particles) through
space or matter - Answer✔️✔️-Electromagnetic radiation

Electromagnetic radiation - Answer✔️✔️-1. Cosmic rays

2. X-rays

3. Microwaves, radio waves

4. Gamma rays

5. Ultraviolet rays

Charge of anode - Answer✔️✔️-Positive

Focal spot is made of - Answer✔️✔️-Tungsten target

Action of anode - Answer✔️✔️-Converts bombarding electrons into x-Ray
photons

What happens when electrons strike tungsten target - Answer✔️✔️-Energy
of motion is converted to x-Ray energy and heat
