radiographic |
|
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. |
