In condensed matter physics, scintillation (/ ˈsɪntɪleɪʃən / SIN-til-ay-shun) is the physical process where a material, called a scintillator, emits ultraviolet or visible light under excitation from high energy photons (X-rays or gamma rays) or energetic particles (such as electrons, alpha particles, neutrons, or ions). [1][2] See ...

The meaning of SCINTILLATION is an act or instance of scintillating; especially : rapid changes in the brightness of a celestial body.

Ionospheric scintillation is the rapid modification of radio waves caused by small scale structures in the ionosphere. Severe scintillation conditions can prevent a GPS receiver from locking on to the signal and can make it impossible to calculate a position.

Scintillation can refer to: Scintillation (astronomy), atmospheric effects which influence astronomical observations Interplanetary scintillation, fluctuations of radio waves caused by the solar wind Scintillation (physics), a flash of light produced in certain materials when they absorb ionizing radiation

A scintillator (/ ˈsɪntɪleɪtər / SIN-til-ay-ter) is a material that exhibits scintillation, the property of luminescence, [1] when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate (i.e. re-emit the absorbed energy in …

Scintillation is defined as a flash of light emitted when a substance is struck by radioactive material. You might find these chapters and articles relevant to this topic. Some crystalline materials emit a large number of light photons upon the absorption of ionizing radiation.

Dec 14, 2019 · Scintillation is a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an ion, or a high-energy photon).

Bombardment of materials by high-energy particles often leads to light emission in a process known as scintillation. Scintillation has widespread applications in medical imaging, x-ray nondestructive inspection, electron microscopy, and high-energy particle detectors.

Scintillation is a flash of light produced in a transparent material by passing a particle (an electron, an alpha particle, an ion, or a high-energy photon). Scintillation occurs in the scintillator, a key part of a scintillation detector.

Flashing or sparkling; a subjective sensation as of sparks or flashes of light. 2. In radiation measurement, the light produced by an ionizing event in a phosphor, as in a crystal or liquid scintillator. A camera, somewhat like an x-ray machine, used to photograph internal organs after the patient has been injected with a radioactive material.

Jul 11, 2004 · Scintillation is an example of radioluminescence wherein the absorption of high-energy radiation or particles leads to observable light. Scintillators may be organic and inorganic solids, liquids, and gases; here we limit the discussion to inorganic solid-state detector materials for medical imaging using X-rays and gamma rays.

Scintillators are materials that are able to convert high energy radiation such as X or gamma-rays to a near visible or visible light. They are widely used as detectors in medical diagnostics, high energy physics and geophysical exploration (ref. Knoll).

Mar 21, 2023 · What is a scintillator? A scintillator is a material that emits light when it interacts with ionizing radiation like X-rays, gamma rays, or charged particles. The word “scintillation” …

Mar 4, 2025 · Technically referred to as “ scintillation,” this visual special effect is just variations in temperature and density of high altitude air flows that create a light show for observers on the ground.

random fluctuation of the amplitude, phase, or polarization of an electromagnetic wave. (on a radar display) a slight, rapid shifting of a spot of light or the image of an object about its mean …

Mar 29, 2024 · Rapid fluctuations in the amplitude and phase of electromagnetic or acoustic waves that have propagated through a medium containing fluctuations in refractive index, such as the atmosphere. The most common example of optical scintillation is the "twinkling" of stars observed through the atmosphere.

1. the act of scintillating. 2. a spark or flash. 3. the twinkling or tremulous effect of the light of the stars. 4. a flash of light from the ionization of a phosphor struck by an energetic photon or particle. [1615–25; < Medieval Latin scintillātiō twinkling of the stars. See scintillate, -tion]

The twinkling of stars, or scintillation, occurs because the optical path length of the atmosphere varies in both space and time due to turbulence. This means that when the wavefront from a distant star enters a telescope, it is distorted from the …

Scintillation counting is one of the most important developments in the application of radioisotopes to procedures needed by scientists, physicians, engineers, and technicians from many diverse discipline for the detection and quantitative measurement of radioactivity.

Scintillation is defined as a flash of light emitted when a substance is struck by radioactive material. Detectors may be used for all types of radiation, depending on the particular type of scintillator used and its configuration.

Scintillators are materials that absorb energetic radiation such as gamma rays, X-rays, or neutrons and convert that energy into short bursts of visible photons. These photons are then converted into electrical pulses by photo-detectors.
