Evaluation of genotoxic effect of X-rays on oral mucosa during panoramic radiography
Journal of Indian Academy of Oral Medicine and Radiology, 2015 Introduction: X-rays are potent mutagenic agents capable of inducing both gene mutations and chromosomal aberrations. They act directly on the DNA molecule or indirectly through the formation of reactive compounds that interact with this molecule.

Digital radiography of the chest
Seminars in Roentgenology, 1997 Digital radiography is an appropriate method for both bedside and in-department chest radiographs. Its major advantage in bedside chest radiography is its control of the displayed optical density of these radiographs. With dynamic range control processing, it improves the visibility of tubes and lines superimposed on the mediastinal tissues.
