Chapter 5: Radiation Characteristics
Learning Objectives
At the end of this module chapter, you will be able to:
5.1
- Define the key terms associated with radiation characteristics.
- Describe the effect that the kilovoltage has on the quality of the x-ray beam and identify the range of kilovoltage required for dental imaging.
- Describe how kilovoltage affects the density and contrast of the image.
- Describe how milliamperage influences the quantity of the x-ray beam and identify the range of milliamperage required for dental imaging.
5.2
- Describe how milliamperage influences the quantity of the x-ray beam and identify the range of milliamperage required for dental imaging.
- Describe how milliamperage affects the density of the image and how exposure time and milliamperage are relate
- Describe how kilovoltage, milliamperage, exposure time, and source-to-receptor distance influence the intensity of the x-ray beam.
- Calculate an example of radiation intensity using the inverse square law.
- Explain how the half-value layer determines the penetrating quality of the x-ray beam.
