Gamma radiation (Ɣ) | Frequencies: 30EHz – 300EHz (0.01nm-1pm)

Sources and Uses

  • Nuclear radioisotopes – applications according to production procedures
  • Mined non-enriched nuclear materials (uranium mines)
  • Enriched  radioisotopes for fission
  • Nuclear fission of radioactive material
    • Spontaneous (nuclear weapons)
    • Controlled (reactors)
  • Bursts of gamma rays from collapsing astronomical objects, collapsing galaxies
  • Gamma emission from collision of cosmic radiation with the atmosphere
  • Gamma emission from transformation of particles into electron-positron energy (annihilation)
  • Medical applications: sterilization, planned mutations, clinical monitoring and follow-up
  • Nuclear medicine – Radiotherapy
    • Treatment of tumors, medical tracers for radiography
    • single photon emission computed tomography (SPECT) - 3D imaging in nuclear medicine
    • Positron emission tomography (PET) – tomography of energy released through positron-electron annihilation by gamma emissions (energy of 0.511MeV)
  • Industrial uses: tracers and measuring instruments based on radioactive Co-60 or Cs-137 (tracers), smoke detectors, industrial measurement probes
  • Non-destructive investigation of the internal structure of materials in the refining, mining, chemical, food, detergent and paper industries
  • Nuclear energy, nuclear reactors
  • Military applications, nuclear arms
  • Scientific research: astronomy, space, nuclear engineering, medicine
