| Question | Answer |
| Intensity is the what? | The total energy contained in the x-ray beam in a specific area at a given time |
| Intensity is affected by what? | The kilovoltage, milliamperage, exposure time, and distance. |
| The inverse square law is used to explain what? | How distance affects the intensity of the x-ray beam |
| What is placed in the path of the x-ray beam to reduce the intensity and remove the low-energy x-rays from the beam ? | An aluminum filter |
| The thickeness of aluminum placed in the path of the x-ray beam that reduces the intensity by half is termed what? | Half-value layer |
| Quantity refers to what? | The number of x-rays produced and is controlled by the milliamperage |
| Increased kilovoltage produces x-rays with what? | Increased energy, shorter wavelength, and increased penetrating power |
| Kilovoltage affects what? | Density and contrast |
| Quality refers to the what? | Mean(average) energy or penetrating ability of the x-ray beam and is controlled by the kilovoltage |
| Exposure time also influences what? | The number of X-rays produced |
| Amperage determines what? | The amount of electrons passing through the cathode filament |
| Milliamperage regulates the temperature of the what? | Cathode filament |
| The overall darkness or blackness of an image is called what? | Density |
| The term that describes how dark and light areas are differentiated on an image is called? | Contrast |
| If the target receptor distance is doubled, the resultant beam will be? | One fourth as intense |
| Current kilovoltage range for dental X-ray | 60-70 kV |
| Current milliamperage range used for dental X-rays ? | 60-8 mA |
