WebThe flares are probably ignited when a massive shift in the crust (a starquake) triggers a large-scale untwisting and rearrangement of magnetic-field lines, causing them to snap and release vast amounts of pent-up magnetic energy in the form of gamma rays, X rays, and particles. But theorists lack a detailed understanding of this process. WebMany objects in the universe are too cool and faint to be detected in visible light but can be detected in the infrared. Scientists are beginning to unlock the mysteries of cooler objects across the universe such as planets, cool stars, nebulae, and many more, by studying the infrared waves they emit.

WebNaI (Tl) detectors The thallium-activated sodium iodide detector, or NaI (Tl) detector, responds to the gamma ray by producing a small flash of light, or a scintillation. The scintillation occurs when scintillator electrons, excited by the energy of the photon, return to their ground state. WebA quantity used to indicate the amount of ionization in air produced by x- or gamma-ray radiation. The unit is the roentgen (R). For practical purposes, one roentgen is comparable to 1 rad or 1 rem for X ray and gamma radiation. The SI unit of exposure is the coulomb per kilogram (C/kg). One R = 2.58 x 10-4 C/kg.

WebGamma rays are also produced in the important process of pair annihilation, in which an electron and its antiparticle, a positron, vanish and two photons are created. The photons are emitted in opposite directions and must each carry 511 keV of energy—the rest mass energy ( see relativistic mass) of the electron and positron. Gamma rays can ... WebRadiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells.
