Alpha radiation consists of helium nuclei and is readily stopped by a sheet of paper. Beta radiation, consisting of electrons, is halted by an aluminium plate. Gamma radiation is eventually absorbed as it penetrates a dense material. |

 Beta Radiation Summary
752 words, approx. 3 pages
 Beta radiation is the emission of an electron from the nucleus of a radioactive isotope. This electron comes from one of the neutrons in an unstable nucleus. The weak nuclear force is involved, and the neutron is converted into a proton when the beta... summary from source:

 Beta Particle Summary
380 words, approx. 1 pages
Henri Becquerel discovered the ability of certain materials to give off radiation spontaneously ( radioactivity) in 1896. The logical follow-up question to this discovery was what the nature of that radiation was. At first, Becquerel thought the... summary from source:
 Beta Particle Summary
95 words, approx. 0 pages
An electron emitted by the nucleus of a radioactive atom. The beta particle is produced when a neutron within the nucleus decays into a proton and an electron. Beta particles have greater penetrating power than alpha particles but less than x-ray or... summary from source:
 Beta Particle Summary
44 words, approx. 0 pages
A radioactive particle equivalent to an electron. It has a mass 1/1836 that of a PROTON and carries a negative charge. Some beta particles carry a positive charge; if so, they are known as positrons. See also: ALPHA PARTICLE; GAMMA RADIATION;... summary from source:
Beta Rays Summary
35 words, approx. 0 pages
These are negatively charged particles (electrons) which move at a high velocity, approaching the speed of light. These particles are not as easily attenuated as are alpha particles and have less ionizing... summary from source:
 Beta particle Summary
388 words, approx. 1 pages
Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei such as potassium-40. The beta particles emitted are a form of ionizing radiation also known as beta rays. The production of beta particles...
