1
,What is the role of filtration in dental radiography?
✔✔To reduce the amount of low-energy X-rays that do not contribute to the image
What is the purpose of the lead collimator in the X-ray tube?
✔✔To focus and limit the X-ray beam
What is the term for the process of absorbing radiation by tissue?
✔✔Attenuation
How does increasing the kilovolt peak (kVp) affect the X-ray beam?
✔✔It increases the energy and penetrating power of the X-rays
What happens to X-ray quality when the milliampere-seconds (mAs) is increased?
✔✔It increases the quantity of X-rays produced, resulting in a darker image

✔✔Radiation that has been deflected from its path due to interaction with matter
2
, What is the role of the tungsten target in the X-ray tube?
✔✔To convert kinetic energy from electrons into X-rays
What is the relationship between wavelength and energy in X-rays?
✔✔Shorter wavelengths correspond to higher energy
What does the term "radiolucent" refer to in dental radiography?
✔✔Areas that appear dark on the radiograph due to lower density
What is the definition of dose equivalent in radiation physics?
✔✔The measurement of biological effect based on the type of radiation and its energy
What is the main function of the lead apron in dental radiography?
✔✔To protect the patient from unnecessary radiation exposure
What is the difference between direct and indirect radiation interaction?
✔✔Direct interaction involves X-rays interacting with atoms, while indirect interaction involves
interaction with water molecules
