In: Physics Share Facebook 4 Answers Voted _YoungMidoriya Added an answer on June 19, 2019 at 12:25 am **Radiation** is energy travelling through space. There are three primary types of radiation: * **Alpha** – these are fast moving helium atoms. They have high energy, typically in the MeV range, but due to their large mass, they are stopped by just a few inches of air, or a piece of paper. * **Beta** – these are fast moving electrons. They typically have energies in the range of a few hundred keV to several MeV. Since electrons are might lighter than helium atoms, they are able to penetrate further, through several feet of air, or several millimeters of plastic or less of very light metals. * **Gamma** – these are photons, just like light, except of much higher energy, typically from several keV to several MeV. X-Rays and gamma rays are really the same thing, the difference is how they were produced. Depending on their energy, they can be stopped by a thin piece of aluminum foil, or they can penetrate several inches of lead. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp BeautyAndGlamour Added an answer on June 18, 2019 at 4:35 pm For the sake of clarity, there are more than 3 types of radiation. The ones you’re thinking of are the ones which typically occur naturally. Here are some forms of ionizing radiation that have been used for therapeutic purposes: * Helium nuclei (“alpha radiation”) * Electrons (“beta radiation”) * Photons (“gamma rays” / “x-rays” / “annihilation photons” / “bremsstrahlung”) * Protons * Neutrons * Heavy nuclei (carbon nuclei, neon nuclei, iron nuclei, etc) * Pions 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Mackowatosc Added an answer on June 18, 2019 at 11:22 am Apart from alpha, beta, and gamma radiation you can also encounter neutron radiation. Which means a stream of energetic neutrons that can both damage molecules, AND have a potential to transmute atoms into their radioactive isotope that will, sooner or later, decay and relase another dose of radiation of some kind. They can also cause some materials to become brittle by damaging some of atoms ( neutron activation leading to decay, leaving either an open space or another atom in its place, with different qualities) in the crystalline structure (thus, creating weakspots) – this is called neutron embrittlement. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Runiat Added an answer on June 18, 2019 at 10:11 am “Radiation” can refer to any sort of travelling – for lack of better synonym – energy, including sound, particle, light, and gravity. The three you’re likely thinking of is alpha, beta, and gamma: Alpha is helium ions ejected from larger atomic nuclei at high velocity, which can knock around the molecules or whatever they hit very powerfully but can be stopped easily. Beta is electrons ejected due to nuclear decay (as opposed to electrons ejected due to all sorts of other reasons) which can knock away other electrons from the molecules they hit and are slightly harder to stop. Gamma is high energy x-rays/photons/light created by nuclear decay (as opposed to x-rays created by electrons) which are very hard to stop and can knock away electrons when you do so. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
