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 | |
16 inch PID is more effective than 16 inch in reducing radiation exposure of the patient | |
Painted cones should not be used because it increases radiation | |
Thyroid collar must be worn for all intraoral exposures |
