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 … Meer weergeven 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 Meer weergeven 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 … Meer weergeven 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 … Meer weergeven X-ray detectors vary in shape and function depending on their purpose. Imaging detectors such as those used for radiography were … Meer weergeven 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 longer wavelength) are called soft X-rays. The intermediate range with photon … Meer weergeven Whenever charged particles (electrons or ions) of sufficient energy hit a material, X-rays are produced. Production by electrons X-rays can … Meer weergeven Since Röntgen's discovery that X-rays can identify bone structures, X-rays have been used for medical imaging.
