The 27 pages that link to Gamma ray, each with the reason it gives.

• Electromagnetic spectrumBroader topic: It represents the high-energy end, though its boundary with X-rays is not absolute.

• Ionizing radiationBroader topic: Gamma rays are another photon form of ionizing radiation, often from nuclear processes.

• Alpha particleCompared with: Gamma rays have no electric charge and penetrate matter far more deeply.

• X-rayCompared with: Gamma rays overlap X-rays in energy but are conventionally distinguished by their nuclear or particle origins.

• PositronRelated: Two gamma rays commonly carry away the energy of electron–positron annihilation.

• Gamma-ray burstNarrower topic: Gamma rays make up the brief, defining prompt signal.

• Food irradiationRelated: Gamma rays from cobalt-60 are a common source for penetrating food treatments.

• Triple-alpha processRelated: The excited carbon-12 nucleus emits a gamma ray as it settles into a stable state.

• Mössbauer spectroscopyNarrower topic: The method uses gamma rays matched to nuclear transition energies.

• Radiation shieldingBroader topic: Gamma rays penetrate deeply, so shielding often requires dense, substantial barriers.

• James ChadwickCompared with: The gamma-ray explanation could not account for the observed proton recoil at plausible energies.

• Gamma-ray spectroscopyNarrower topic: Gamma-ray spectroscopy measures these photons rather than the charged particles often emitted alongside them.

• Cobalt-60Broader topic: Excited nickel-60 releases gamma rays as it settles into a lower-energy state.

• RadiotoxicityBroader topic: Its penetrating radiation can expose the body from an external source.

• Single-photon emission computed tomographyRelated: Gamma rays escaping the body are the signals detected in SPECT.

• Beta particleCompared with: Unlike beta particles, gamma rays have no electric charge or rest mass.

• Neutron activationRelated: Many activated nuclides emit characteristic gamma rays as they decay.

• Radiogenic heatRelated: Gamma photons can carry energy away from a decay site before depositing it as heat.

• Neutron radiationCompared with: Gamma rays interact chiefly with electrons and nuclei, unlike neutral neutrons, which can trigger nuclear reactions.

• Cowan–Reines neutrino experimentRelated: Gamma rays from positron annihilation and neutron capture formed the detector’s light-producing signals.

• Discovery of the neutronCompared with: Gamma rays were the leading alternative explanation for beryllium’s penetrating radiation.

• Rudolf MössbauerNarrower topic: Gamma rays carry the sharply defined energies required for nuclear resonance absorption.

• Dirty bombRelated: Gamma emissions can penetrate bodies and structures more readily than alpha particles.

• Victor HessRelated: Early explanations considered penetrating gamma radiation as a possible source of atmospheric ionization.

• Caesium-137Broader topic: The gamma ray from barium-137m drives many exposure and measurement concerns.

• Cosmic rays and astroparticlesBroader topic: Gamma rays trace particle interactions but are not deflected by magnetic fields.

• Gamma-ray techniquesNarrower topic: It is the radiation these techniques produce, detect, or apply.
