WitrynaAn 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 16 Hz to 3 × 10 19 Hz) and energies in the range 145 eV to 124 keV.X-ray … WitrynaIonising radiation is a form of electromagnetic radiation with enough energy to dislodge outer shell electrons from an atom, causing that atom to become ionised and charged. 1 In practice, ionising radiation for medical imaging includes X-ray, CT, fluoroscopy and angiography. Ultrasound and magnetic resonance imaging (MRI) do not use ionising ...
