radiograph | - An image produced on film or another sensitive surface when radiation such as x-rays or gamma rays passes through an object verb to make a radiograph of something, especially a part of the body
- X ray.
|
|
radiograph (rt) | A permanent visible image on a recording medium produced by penetrating radiation passing through the material being tested. |
|
radiographer | - 1. a person specially trained to operate a machine to take x-ray photographs or radiographs. also called diagnostic radiographer 2. a person specially trained to use x-rays or radioactive isotopes in the treatment of patients. also called therapeutic radiographer
- Any individual who performs or who, in attendance at the site where the sealed source or sources are being used, personally supervises radiographic operations and who is responsible to the licensee for assuring compliance with the requirements of these regulations and the conditions of the licenses.
- Person that performs, supervises, and is responsible for industrial radiologic test operations.
|
|
radiographer’s assistant | Any individual who under the personal supervision of a radiographer, uses radiographer exposure devices, sealed sources or related handling tools, or survey instruments in radiography. |
|
radiographer’s exposure device | Any instrument containing a sealed source fastened or contained therein, in which the sealed source or shielding thereof may be moved, or otherwise changed, from a shielded to unshielded position for purposes of making a radiographic exposure. |

|
|
radiographic code | A code for specifying minimum standards related to radiographic practices. |
|
radiographic contrast (rt) |
|
|
radiographic equivalence factor (rt) | The factor by which the thickness of material must be multiplied in order to determine what thickness of a standard material (often steel) will have the same absorption. |
|
radiographic exposure device (rt) |
|
|
radiographic film |
|
|
radiographic film (rt) |
|
|
radiographic inspection | Рентгенографический контроль |
|
radiographic inspection (rt) | The use of x-rays or nuclear radiation or both to detect discontinuities in material, and to present their images on a recording medium. |
|
radiographic interpretation (rt) | The identification of subsurface discontinuities indicated on the radiograph. the evaluation as to the acceptability or reject ability of the material is based upon the judicious application of the radiographic specifications and standards governing the material. |
|
radiographic paper (rt) | White paper coated on one side with emulsion, suitable for some purposes as an alternative to x-ray film. |
|
radiographic projection method (rt) | A method whereby image magnification is achieved by projection. |
|
radiographic qualification test | A procedure for determining the optimum value of the d/t ratio, or the proper working distance of an x-ray tube or a radioactive source. |
|
radiographic quality level |
|
|
radiographic quality level (rt) | An expression of the quality (sensitivity) of a radiograph in terms of an image quality indicator (penetrameter). when a standard hole-type penetrameter is used, quality level is stated as a-bt, where a is the penetrameter thickness, expressed as a percentage of the maximum thickness of the specimen, and b is the diameter of the smallest discernible hole, expressed as a multiple of penetrameter thickness, t. for example, the 3- 2t quality level means that the penetrameter thickness equals 3 percent of maximum specimen thickness, and the smallest discernible penetrameter hole has a diameter equal to twice the penetrameter thickness. |
|
radiographic radiographic definition (rt) |
|
|
radiographic range (rt) |
|
|
radiographic screen (rt) |
|
|
radiographic screens | Metallic or fluorescent sheets are used to intensify the radiation effect on films. |
|
radiographic sensitivity (rt) |
|
|
radiographic technique (rt) | The selection of those radiographic factors such as kilovoltage, milliamperage, type of film and screen, distance, and exposure time to render the best possible radiographic sensitivity. |
|
radiographic template |
|
|
radiographic test |
|
|
radiographically similar material (rt) | A material or alloy that has approximately the same radiation absorption as the material being radiographed. |
|
radiographische analyse; radiographie |
|
|
radiography | - Radiografía
- The work of examining the internal parts of the body by taking x-ray photographs
- See radiologic testing. radiologic testing (rt): use of penetrating radiant energy in the form of x-rays, gamma rays, or neutrons for nondestructive testing of objects to provide images of the objects’ interiors. also called radiography; radiographic testing.
|
|
radiography (rt) | A nondestructive testing method wherein a source of x-rays or gamma rays, is utilized to indicate the subsurface condition of opaque materials. a permanent record of the soundness characteristics is generally made on a specially prepared film called the radiograph. |
