- In 1912 it was shown that the much more penetrating gamma rays have all the properties of very energetic electromagnetic radiation, or photons. Gamma-ray photons are between 10,000 and 10,000,000 times more energetic than the photons of visible light when they originate from radioactive atomic nuclei.

Mar 30, 2024 · The attenuation of X-rays and gamma rays in matter depends on the energy of the radiation and the density and atomic number of the material. Higher-energy photons are more penetrating, while denser, higher-Z materials are more effective at stopping these types of radiation.
Gamma rays have the shortest wavelengths and highest energies among the electromagnetic spectrum. Their wavelengths range from about 10 picometers (pm) to less than 1 femtometer (fm). In contrast, X-rays have longer wavelengths, typically ranging from 0.01 to 10 nanometers (nm).
In astrophysics, gamma rays are conventionally defined as having photon energies above 100 keV and are the subject of gamma-ray astronomy, while radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy.
Nov 3, 2024 · A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than a few tenths of an angstrom (10 −10 meter), and gamma-ray photons have energies greater than tens of thousands of electron volts.
