| Filters in dental x-ray tube head do what | remove all low energy x-rays |
| Inherent filtration | when only glass windows, oil, and tube housing (built in filters) |
| Added filtration | placement of aluminum disks |
| Most effective method of reducing radiation | fast films |
| Which PID device is most effective in reducing patient exposure | Rectangular PID |
| What restricts size and shape of x-ray beam | collimater |
| What material is used as a collimater | lead |
| Describe function of filtration | reduced low energy waves |
| Recommended size of beam at patients face | 2.75 inches |
| Dose of radiation the body can endure without injury is called | maximum permissible dose |
| Radiation monitor badge | personal monitoring device used to measure x-radiation |
| Every patient should be evaluated individually for radiographs | |
