İngilizce - İngilizce
A positively charged nucleus of a helium-4 atom (consisting of two protons and two neutrons), emitted as a consequence of radioactivity
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
A particle identical to the helium nucleus which has been ejected from the nucleus of an atom as a form of radiation When the alpha particle slows down it picks up two electrons, becoming an atom of helium The penetrating power of an alpha particle is low; a thin sheet of paper will stop most alpha particles The readjustment which takes place within the parent nucleus results in gamma radiation
A particle emitted from the nucleus of an atom, containing two protons and two neutrons, identical to the nucleus (without the electrons) of a helium atom
Helium nucleus: two protons, two neutrons, NO electrons Alpha particles are ions
Positively charged particle emitted by certain radioactive substances during their radioactive disintegration An alpha particle consists of two neutrons and two protons and is identical to the nucleus of a helium atom Alpha radiation is less penetrating than beta or gamma radiation A sheet of paper is sufficient to absorb alpha radiation
positively charged particle made up of two protons and two neutrons, nucleus of a helium atom
Charged particles emitted from a radioactive atom Each charged particle consists of two protons and two neutrons
A positively charged particle ejected spontaneously from the nuclei of some radioactive elements It is identical to a helium nucleus that has a mass number of 4 and an electrostatic charge of +2 It has low penetrating power and a short range (a few centimeters in air) The most energetic alpha particle will generally fail to penetrate the dead layers of cells covering the skin and can be easily stopped by a sheet of paper Alpha particles are hazardous when an alpha-emitting isotope is inside the body
The nuclei of a helium atom (with two neutrons and two protons each) that are discharged by radioactive decay of many heavy elements, such as uranium-238 and plutonium-239
