alpha particle
A helium-4 nucleus, especially when emitted from the nucleus of a radioactive atom
A positively charged particle, emitted by certain radioactive materials, made up of two neutrons and two protons bound together, hence identical with the nucleus of the helium atom; the least penetrating of the three common types of radiation (alpha, beta, gamma), it is stopped by a sheet of paper Not dangerous to plants, animals or humans unless the alpha-emitting substance has entered the body
A positively charged nuclear particle identical with the nucleus of a helium atom It consists of two protons and two neutrons and is ejected at high speed from the nucleus of an atom in certain radioactive transformations
A positively charged particle emitted from the nucleus of an atom having the same charge and mass as that of a helium nucleus (two protons and two neutrons)
A positively charged particle emitted in the radioactive decay of certain radioactive atoms An alpha particle is identical to the nucleus of the helium atom *
a positively charged particle that is the nucleus of the helium atom; emitted from natural or radioactive isotopes
A small electrically charged particle of very high velocity thrown off by many radioactive matierials, including uranium and radium It is identical with the nucleus of a helium atom and is made when an atom is fissioned Also see: Beta particle, Gamma rays
A positively-charged particle from the nucleus of an atom, emitted during radioactive decay
A positively charged particle consisting of two protons and two neutrons emitted by one of the radioactive elements An alpha particle is equivalent to an He2+ ion
A particle consisting of two protons and two neutrons, produced during alpha decay Identical to the nucleus of a 4He atom
helium nucleus emitted from a heavy radioactive element
The nuclei of a helium (with two neutrons and two protons each) that are discharged by radioactive decay of many heavy elements, such as uranium-238 and plutonium-239
A positively-charged particle from the nucleus of an atom, emitted during radioactive decay Alpha particles are helium nuclei, with 2 protons and 2 neutrons
Two neutrons and two protons bound as a single particle emitted from the nucleus of certain radioactive isotopes in the process of decay or disintegration
A particle emitted spontaneously from the nuclei of some radioactive elements It is identical with a helium nucleus, having a mass of four units and an electric charge of two positive units See Radioactivity
A positively charged particle emitted by certain radioactive materials [see radioactive materials definition] It is made up of two neutrons [see neutrons definition] and two protons [see protons definition] bound together and, hence, is identical to the nucleus of a helium atom It has low-penetrating power and short range The most energetic alpha particle will generally fail to penetrate the skin (Health Physics and Radiological Health Handbook Nuclear Lectern Associates, 1984 ) Back to Top
A positively charged particle, indistinguishable from a helium atom nucleus and consisting of two protons and two neutrons
A specific particle ejected from a radioactive atom It has low penetrating power and short range Alpha particles will generally fail to penetrate the skin Alpha-emitting atoms can cause health effects if introduced into the lungs or wounds
A particle from the nucleus of an atom with a positive charge that is emitted during radioactive decay They consist of helium nuclei with 2 protons and 2 neutrons
A 4He nucleus It is made up of two neutrons and two protons It is the least penetrating of the three common forms of radiation, being stopped by a thin sheet of paper It is not dangerous to living things unless the alpha-emitting substance is inhaled or ingested or comes into contact with the lens of the eye
