Gamma rays are typically produced by the decay from high energy states of atomic nuclei, called gamma decay, but they are also created by other processes. For instance, gamma rays are also produced by secondary radiation from atmospheric interactions with cosmic ray particles. Also, rare terrestrial natural sources produce gamma rays that are not of a nuclear origin, like lightning strikes and terrestrial gamma-ray flashes. Plus, they are produced by astronomical processes where very high-energy electrons are produced that cause secondary gamma rays via bremsstrahlung, inverse Compton scattering and synchrotron radiation.
Gamma rays are produced by high-energy processes such as nuclear reactions, supernovae explosions, and the annihilation of particles. They are the most energetic form of electromagnetic radiation and have the shortest wavelengths in the electromagnetic spectrum.
Supernovae and active black holes are by far the most interesting gamma ray emitters. Active black holes can actually focus them into rays of death, and supernovae which form black holes can briefly shine brightly enough that we can see them here even if the entire combined light from every other object in that galaxy is too dim for us to see. They're also emitted by some types of nuclear decay, but you're not likely to come into contact with them. The fact that a single one can cause significant damage to a cell leads us to try to avoid them. Uranium decay is a pretty good source of them.
most radioactive materials
alpha radiation = high-energy alpha particle leaves core
beta radiation = neutron turns into proton, shooting high-energy elektron out of the atom
gamma radiation = energy released from alpha and beta(and K-capture, elektron from K-shell gets caught in core, reacting with a proton to form a neutron) radiation by mass-reduction caused by nuclear decay
Gamma rays are emitted by a couple of means:
1) They are emitted from the atomic nucleus as a means of removing excess energy from an excited nucleus. Often emitted simultaneously (or immediately after) alpha/beta (eg I-131, beta+gamma), but can be several hours later in the case of isomeric transition (eg Tc-99m, IT).
2) Annihilation radiation is (as far as I know) categorised as gamma radiation. This is most commonly observed after positron emission (beta+ decay). A positron is antimatter and will inevitably annihilate with an electron when travelling slowly and in close proximity. This results in two identical gamma rays emitted each has energy equivalent to the rest-mass energy of an electron (or positron; they're the same). A great practical use of this is in PET scanning.
gamma radiation, is caused by particles that can go through aluminium but leed, or a few centimetres of concrete.
Gamma rays originate from the decay of radioactive substances
Gamma Rays
Gamma rays have a higher frequency than X-rays. Gamma rays are the most energetic form of electromagnetic radiation in the electromagnetic spectrum, whereas X-rays have a lower frequency than gamma rays.
X-rays have lower energy than gamma rays. Gamma rays are a form of high-energy electromagnetic radiation, while x-rays have lower energy and shorter wavelengths than gamma rays.
The electromagnetic waves with the highest frequencies are called gamma rays. They have the shortest wavelengths and highest energy levels among all types of electromagnetic radiation.
Radiation emitted during nuclear decay produces rays that travel in all directions. This occurs when an unstable nucleus releases energy in the form of gamma rays, which are electromagnetic waves with high energy. Gamma rays can travel in all directions from the source of decay.

Gamma Rays
no gamma rays are the best
Cathode rays generate x-rays and gamma rays are electromagnetic radiation. Gamma rays have very high penetration power.
gamma rays are Vincent is weird
X-rays and gamma rays are forms of electromagnetic radiation with high energy and short wavelengths. X-rays are commonly used in medical imaging and security screening, while gamma rays are typically associated with nuclear reactions and radioactive decay. Both types of radiation can penetrate materials and tissues, but gamma rays have higher energy levels and are more penetrating than x-rays.
No, gamma rays are not neutrons. They are electromagnetic rays or electromagnetic energy.
It can't, as far as I know. "Gamma decay" doesn't refer to the decay of gamma rays; rather, it refers to a decay of ATOMS, or some other particles, which produces gamma rays in the process.
Ultraviolet (UV) radiation is an electromagnetic wave that can create ions by removing electrons from atoms or molecules. This process is called ionization.
Yes, gamma rays are high-energy electromagnetic radiation that can be used for various applications such as cancer treatment, sterilization of medical equipment, and imaging techniques like PET scans. However, they can be harmful if not properly shielded against.
