An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 Hz to 3×10 Hz) and energies in the range … See more Pre-Röntgen observations and research Before their discovery in 1895, X-rays were just a type of unidentified radiation emanating from experimental discharge tubes. They were noticed by scientists investigating See more X-ray photons carry enough energy to ionize atoms and disrupt molecular bonds. This makes it a type of ionizing radiation, and therefore harmful to living tissue. A very high radiation dose over a short period of time causes radiation sickness, while lower doses can … See more Whenever charged particles (electrons or ions) of sufficient energy hit a material, X-rays are produced. Production by … See more X-ray detectors vary in shape and function depending on their purpose. Imaging detectors such as those used for radiography were … See more Soft and hard X-rays X-rays with high photon energies above 5–10 keV (below 0.2–0.1 nm wavelength) are called hard X-rays, while those with lower energy (and … See more X-rays interact with matter in three main ways, through photoabsorption, Compton scattering, and Rayleigh scattering. The strength of these interactions depends on the energy of the X-rays and the elemental composition of the material, but not much on chemical … See more Since Röntgen's discovery that X-rays can identify bone structures, X-rays have been used for medical imaging. The first medical use was less than a month after his paper on the subject. Up to 2010, five billion medical imaging examinations had been conducted … See more WebDec 14, 2024 · Most X-rays have a wavelength ranging from 0.01 to 10 nanometers (3×10 16 Hz to 3×10 19 Hz), corresponding to energies in the range 100 eV to 100 keV.
