| position indicating device | x-ray tube or cone |
| control panel | the portion of the x-ray device that houses the main buttons |
| developer | the chemical solution used in film processing that makes the latent image visible |
| dosimeter | a small device used to measure the amount of accumulated radiation taken in by a dental health care worker |
| electron | a small negatively charged particle of the atom containing much energy and little mass |
| emulsion speed | the sensitivity of a fim to the radiation exposure |
| extraoral | outside the mouth |
| fixer | the chemical solution used to stop the processing of the film and makes the image that has appeared permanent |
| hard radiation | rays of high energy and extremely short wavelengths |
| incandescence | the stage in which the tungsten filament becomes red hot and glows |
| intraoral | inside the mouth |
| leakage radiation | the x-rays that escape out of the tube headd at places other than the opening |
| panoramic | a type of x-ray that moves around its target as the target stays still |
| periapical radiograph | a radiograph that shows the complete tooth or teeth in a region |
| primary beam | the original undeflected useful beam of radiation that emanates the focal spot of the x-ray tube and emerges through the end of the tube head |
| processing | a way of bringing out the image and making it permanently visible |
| reticulation | cracking of the films emulsion caused by a large temperature change during developing |
| safelight | a special type of filtered light that can be left on while in the darkroom |
| scatter radiation | radiation that has been deflected from its path by impact during its passage through matter |
| secondary radiation | the radiation given off by any matter irradiated with x-rays |
