Properties of X-rays
| Question | Answer |
|---|---|
| Primary Componets | Tubehead, extension arm , control panel |
| Tubehead | contains the x-ray tube that produces dental x-rays |
| Metal housing | the metal body of the tubehead; houses the x-ray tube. |
| Cathode (-) | consist of tungsten filament in a focusing cup made of molybdenum |
| The hotter the filament becomes | the MORE electrons are produced |
| Anode | The target for electrons |
| PID | Position indicator Device |
| Control Panel | Master switch , an indicator light, selector button , and exposure button. |
| Exposure button | Located on a wall OUTSIDE the x-ray area to the operator during film exposure |
| Selector Button | Used to selected the exposure time , milliamperage (mA) and Kilovotage (kV) |
| Milliamperage Selectr "MA Selector" | Measure of the electrical current |
| Dental Images | internal images of your teeth and jaws. |
| Kilovoltage selector (kVp) | control the penettrating the power of the x-ray beam. |
| Dental x-rays generally have operate at? | 70 or 90 kvp |
| The filament circuit uses | 3 to 5 volts |
| No interaction | A photon phases through matter without being scattered or absorbed and an continue its path to create density on a film or sensor |
| Photoelectric effect |
