Parent topics

• Ionizing radiation [r]: Subatomic particles or electromagnetic waves that are energetic enough to detach electrons from atoms or molecules, ionizing them. ^[e]
  • Alpha particle [r]: helium nucleus; particle of charge 2e and mass 4 u. ^[e]
  • Beta particle [r]: A high-energy electron or positron emitted, along with a neutrino, by the decay of an atomic nucleus; a form of ionizing radiation ^[e]
  • Neutron [r]: An elementary particle of neutral charge, normally found in the nucleus of chemical elements, but having significant effects when in free flight; the number of neutrons in the nucleus of an element defines its identity as an isotope ^[e]
  • X-ray [r]: An ionizing type of electromagnetic radiation whose absorption or diffraction often used for structural investigations of matter. ^[e]
  • Gamma ray [r]: Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during nuclear decay. ^[e]
• Nuclear MASINT [r]: Add brief definition or description

Subtopics

Detectors

• Ionization detector [r]: A device whose filler changes conductivity, in a measurable way, when struck by ionizing radiation ^[e]
  • Geiger-Mueller tube [r]: Ionization detectors built around a gas-filled metal tube, with a wire charged to approximately +1000 volts down the center of the tube ^[e]
• Excitation detector [r]: A device or material that emits some form of visible light when struck by ionizing radiation of certain types and energy levels ^[e]
  • Thermoluminescent dosimeter [r]: Add brief definition or description
  • Scintillating material [r]: A material that emits distinct bursts of light when struck by ionizing radiation of certain types and energies ^[e]
    • Sodium iodide [r]: Add brief definition or description
    • Zinc sulfide [r]: Add brief definition or description

Instruments and techniques

• Gamma spectrometry [r]: Methods in nuclear chemistry and radiation analysis that measure the characteristics of quanta of gamma rays from a source; the analysis is not direct on the gammas, but typically on an effect caused by them, such as the rates and energy distribution of specific gamma quanta impacting on a scintillating material and producing light to be measured ^[e]

Other related topics

• Phosphor [r]: A material that produces visible light when impacted by ionizing radiation, electrons, or other energies outside the visible spectrum; the emission of light may be tailored to have long or short persistence in time ^[e]

Imaging devices that use radioactivity

• Radiology [r]: A physician specialty with a core competence in obtaining and diagnosing by means of instruments that receive energy transmitted through the body; there are a number of subspecialties. ^[e]
• Nuclear medicine [r]: That medical specialty, or subspecialty, concerned with diagnosis and treatment using radioisotopes administered to the patient ^[e]
• Anger camera [r]: A device used to form images from the bursts of light generated by collimated gamma rays striking a scintillating material, typically in nuclear medicine ^[e]
• Single photon emission computed tomography [r]: A nuclear medicine imaging technique that visualizes the metabolism, or lack thereof, of tissues into which a photon-emitting tracer has been absorbed ^[e]
• X-ray computed tomography [r]: Three-dimensional medical imaging method, employing tomography created by computer processing. ^[e]
• Positron emission tomography [r]: Add brief definition or description
