Principles of X-rays (1960)

Wilhelm Röntgen’s accidental discovery of X-rays in 1895 revolutionized science and medicine. While repeating an experiment on cathode rays, he observed a mysterious fluorescence emanating from his equipment, far beyond the reach of the known rays. This led him to investigate a new, penetrating form of radiation, which he termed X-rays. His initial experiments revealed their ability to pass through solid objects, famously producing the first radiograph of his wife’s hand. The medical community quickly recognized the diagnostic power of X-rays, leading to their widespread adoption in surgery and treatment. Further research by scientists like Laue and the Braggs established X-rays as electromagnetic waves with wavelengths shorter than ultraviolet light, and their diffraction by crystals opened up the field of X-ray crystallography, providing insights into atomic structure and the composition of matter. Today, X-rays are a crucial tool in non-destructive testing, industrial quality control, and advanced medical imaging.
