Ionizing radiation includes alpha particles (a high-speed helium nucleus), beta particles (a high-speed electron or positron), gamma rays, X-rays, and galactic cosmic radiation (GCR).

In the 1920s, physicists were confused: the phenomenon of β decay (in which an electron is emitted from the atomic nucleus) seemed to violate conservation laws. The energy spectrum of the ...

The circle in the middle of the trefoil represents an atom and the blades represent the three common types of ionizing radiation emanating from it - alpha (α), beta (β) and gamma (γ). The symbol was ...

The Neutron Activation Analysis is a very sensitive method for determination of element content and composition. However, conventional methods do not provide information regarding the spatial ...

Ward J. DNA damage produced by ionizing radiation in mammalian cells: identities, mechanisms of formation and repairability. Prog Nuclei Acid Res Mol Biol. (1988) 35:95–125. doi: 10.1016/S0079-6603 ...

Alpha, beta, and gamma are all types of ionizing radiation, in that they can kick an electron out of an atom. However, with neutron radiation a neutron is ejected from a radioactive nucleus.

Cerenkov radiation (CR) has been used in various biological research fields, which has aroused lots of attention in recent years. Combining optical imaging instruments and most of nuclear medicine ...

This radiation received its name — gamma-rays — simply because gamma is the third letter in the Greek alphabet after alpha and beta. Unbeknownst to Villard and his cohorts in the early 1900s ...

A beta particle is an electron or positron that travels at a high energy and high speed. Both of these particles are emitted by elements that are undergoing radioactive decay.

Ionizing radiation is a type of particle radiation in which an individual particle (for example, a photon, electron, or helium nucleus) carries enough energy to ionize an atom or molecule (that is ...

Likely four-quark particle spotted by Beijing Electron Positron Collider has never been seen before.
