 Alpha Particle Summary
903 words, approx. 3 pages
 The alpha particle is emitted by certain radioactive elements as they decay to a stable element. It consists of two protons and two neutrons; it is positively charged. The element that undergoes "alpha decay" changes into a new element whose atomic... summary from source:

Alpha Radiation Summary
595 words, approx. 2 pages
Alpha radiation is the stream of alpha particles emitted when radioactive materials disintegrate. When radioactive material breaks down, there is a loss in the total mass of the products. According to the law of conservation of mass-energy there must... summary from source:
 Alpha Particle Summary
376 words, approx. 1 pages
The earliest studies of nuclear radiation suggested that it consisted of at least one kind of charged particle. Various experiments showed that nuclear radiation can be deflected by a magnetic field. This finding confirms that at least some part of the... summary from source:
 Alpha Particle Summary
95 words, approx. 0 pages
A particle emitted by certain kinds of radioactive materials. An alpha particle is identical to the nucleus of a helium atom, consisting of two protons and two neutrons. Some common alpha-particle emitters are uranium-235, uranium-238, radium-226, and... summary from source:

A radioactive particle equivalent to the nucleus of a helium atom, i.e. comprising two protons and two neutrons, and emitted by a RADIONUCLIDE. See also: BETA PARTICLE; GAMMA RADIATION; IONISING... summary from source:
Alpha Ray Summary
29 words, approx. 0 pages
These are not true rays but are particles of matter. They are double charged ions of helium and are easily attenuated but have strong ionizing... summary from source:
 Alpha particle Summary
1,025 words, approx. 3 pages
Alpha particles (named after and denoted by the first letter in the Greek alphabet, α) consist of two protons and two neutrons bound together into a particle identical to a helium nucleus; hence, it can be written as He2+ or 42He. They are a highly...
