About Primordial Nuclide

About Primordial Nuclide Definition Primordial Nuclides or primordial isotopes are nuclides found on the earth that have existed in their current form since before Earth was formed, according to stellar evolution theory. Due to the age of the Earth of 4.58×109 years, this means that the half-lif.....

About Beta Decay

About Beta Decay Definition Beta Decay is a radioactive process in which an electron is emitted from the nucleus of a radioactive atom, along with an unusual particle called an antineutrino. The neutrino is an almost massless particle that carries away some of the energy from the decay process. B.....

About Alpha Decay

About Alpha Decay Definition Alpha decay (α decay) is the phenomenon of emission of an alpha particle from a radioactive nucleus. When a nucleus emits an alpha particle then its mass number decreases by 4 and the charge number is decreases by 2. Alpha decay is a type of Radioactive decay is a sp.....

About Ionizing Radiation

About Ionizing Radiation Definition Ionizing Radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized. It also called radioactivity, is electromagnetic (EM) .....

About Radioactive Elements

About Radioactive Elements Definition Radioactive element does not have any stable isotopes, which means it may spontaneously degenerate. Radioactive elements include uranium, curium and thorium. Radioactive elements are just like the other elements. They are made of neutrons, protons, and electr.....

About Cyclotron

About Cyclotron Definition Cyclotron is a type of particle accelerator that uses a constant magnetic field to hold charged particles in a circular spiral pattern. The first cyclotron was invested at the University of California, Berkeley, in 1932, by Ernest Lawrence in collaboration with his stud.....

About Cherenkov radiation

About Cherenkov radiation Definition Cherenkov radiation is named after the Russian physicist who first worked it out in detail, in 1934, Pavel Alekseyevich Cherenkov, he got a Nobel for his work, in 1958, and it’s also sometimes called Cerenkov radiation. It is electromagnetic radiation emitte.....

About Antiproton

About Antiproton Definition Antiproton is actually stable but still of short life as any collision with proton means destruction of both with sudden burst of energy. It is also called negatron. Antiprotons were first produced and identified in 1955 by Emilio Segrè, Owen Chamberlain, for which th.....

About Bubble Chamber

About Bubble Chamber Definition Bubble Chamber is a chamber of superheated liquid in which the path of an ionizing particle is made visible by a string of vapor bubbles. It is designed to detect charged particles through the tracks of bubbles present in a chamber consisting of liquefied gas or li.....

About Gamma Radiation

About Gamma Radiation Definition Gamma Radiation is very high-energy ionizing radiation. Gamma rays originate in the nucleus, while X-rays originate in the electron cloud around the nucleus. Gamma-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, ultraviolet ra.....
