| Question | Answer |
|---|---|
| Which of the following are the prime factors of exposure in radiography? | Milliamperage, exposure time, kilovoltage, and distance (SID) |
| The unit used to indicate the total quantity of x-rays in an exposure is | mAs |
| If an image were made using 500 mA, 0.1 seconds, and 75kVp, what would the mAs be for this exposure? | 50 mAs |
| if the radiographic image is overexposed, which of the following changes in exposure factors should be used to correct the problem? | decrease mAs |
| the distance between the tube target and the IR is termed | source-image distance (SID) |
| The inverse square law governs the relationship between | X-ray beam intensity and distance |
| The inverse square law states that the intensity of the x-ray beam is_____ to the square of the distance. | inversely proportional |
