These include the nature of the subject, the characteristics of the film and/or the IR, and the amount of scatter radiation impacting the IR. High kilovoltage produces an x-ray beam that penetrates more completely, leaving no white areas in the image. The dark, easily penetrated portions of the subject are not quite as dark when the kVp is high because less rnAs is needed to obtain the desired radiographic density. When more (higher) contrast is desired, the kVp is decreased. Because this will result in less penetration by the x-ray beam, a beam of greater intensity is needed, and the mAs must be increased.
Cassettes are marked according to the type of screens they contain, and the technique chart will state which screens are appropriate with a given set of exposures. Intensifying screens are quite expensive and are easily damaged. Damaged areas, dirt, or stains on the screens prevent light from exposing the film and result in artifacts on the image. For these reasons, it is important to avoid touching the screens and to keep the film processing area free of dust and dirt. Film Radiographic film is manufactured with a particular sensitivity to the light emitted by intensifying screens.
RADIATION UNITS AND MEASUREMENT Radiation measurements can be made in two different, but related, systems: the traditional (British) system, still commonly used in the United States, and the Systeme Internationale (SI) units established by the International Commission on Radiation Units in 1981. These units and their relationships are summarized in Table 1-2. The traditional unit of radiation exposure is the roentgen (R), a measurement of radiation intensity in air. 08 x lo9 (more than 2 billion) ion pairs in 1 cm3 of dry air.
