Speed of gamma rays

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. See more A gamma ray, also known as gamma radiation (symbol γ or $${\displaystyle \gamma }$$), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the … See more The first gamma ray source to be discovered was the radioactive decay process called gamma decay. In this type of decay, an excited nucleus emits a gamma ray almost immediately upon formation. Paul Villard, a French chemist and physicist, … See more Penetration of matter Due to their penetrating nature, gamma rays require large amounts of shielding mass to reduce … See more Gamma rays cause damage at a cellular level and are penetrating, causing diffuse damage throughout the body. However, they are less ionising than alpha or beta particles, which are … See more Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotopes such as potassium-40, and also as a secondary radiation from various atmospheric … See more Gamma rays provide information about some of the most energetic phenomena in the universe; however, they are largely absorbed by the Earth's atmosphere. Instruments aboard high-altitude balloons and satellites missions, such as the Fermi Gamma-ray Space Telescope See more The following table shows radiation quantities in SI and non-SI units: The measure of the ionizing effect of gamma and X-rays … See more WebIn 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.
