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 shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 … 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. 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 Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotopes such as potassium-40, … See more Penetration of matter Due to their penetrating nature, gamma rays require large amounts of shielding mass to reduce them to levels which are not harmful to living … 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 less penetrating. Low levels of gamma rays cause a stochastic health … See more The conventional distinction between X-rays and gamma rays has changed over time. Originally, the electromagnetic radiation emitted by X-ray tubes almost invariably had a longer wavelength than the radiation (gamma rays) emitted by radioactive See more WebBecause gamma radiation has no mass and is purely energy, that means it has no protons or electrons, which also means it has no electric charge. So, let’s say that we were looking at a nuclear equation involving gamma decay. Imagine we had a barium-137 isotope, and that this nucleus experienced radioactive decay through gamma radiation.

WebThe two types of radiation are electromagnetic (like light) and particulate (i.e., mass given off with the energy of motion). Gamma radiation and X-rays are examples of electromagnetic radiation. Beta and alpha radiation are examples of particulate radiation. Ionizing radiation can also be produced by devices such as X-ray machines.

What is Radiation? IAEA - International Atomic Energy Agency

WebMar 19, 2024 · Now, let's look at the different kinds of radiation. There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how … WebWhat is the mass of alpha radiation? Alpha radiation has been identified as helium nuclei that have been stripped of their planetary electrons, and each consists of two protons and two neutrons. α particles thus have a mass of about 4 amu (6.642×10 − 4 g) each and a positive charge of 2.
