The distance separating the x-ray tube focus and the grid.  

Linear markings are visible on the final radiograph due to the immobility of the Bucky diaphragm during exposure or its failure to follow the prescribed grid radius.  

The convergence point is the location where all radiopaque strips within a grid would intersect if extended.  

The term refers to the number of distinguishable gray tones perceived by the human eye when transitioning from the darkest shade of black to the brightest shade of white.    

A unit of integral absorbed dose of radiation is referred to as a rad, which is equivalent to 100 ergs per gram.  

The radiograph produces a clear and well-defined image, regardless of whether the image may be over- or underexposed, over- or under-penetrated.  

Exposure to radiation that has harmful effects on future generations. This results from the vulnerability of the genes, particularly chromosomes of sex cells, to radiation damage.  

When discussing “white” radiation or bremsstrahlung radiation, it is important to note that general radiation accounts for approximately 90 percent of the x-rays emitted within the diagnostic range. The remaining 10 percent of emitted x-rays are categorized as characteristic radiation.  

Exposure to radiation can have detrimental effects on the organs responsible for blood formation, including the bone marrow and lymphatic tissues.  

The Kodak safelight filter is designed to be compatible with all blue-sensitive films and the majority of green-sensitive films. It provides illumination comparable to the Wratten 6B standard.
