Record 1 - external organization data 2014-12-30

English

Subject field(s)
  • Compartment - Canadian Nuclear Safety Commission
  • Atomic Physics
DEF

A positively charged nuclear particle identical with the nucleus of a helium atom, consisting of 2 protons and 2 neutrons, having atomic mass 4 and atomic number 2, ejected at high speed in certain radioactive transformations.

OBS

Least penetrating of the three common forms of radioactive substances (alpha, beta, gamma), it is not normally considered dangerous to plants, animals or people unless it gets into the body.

OBS

alpha particle: term standardized by ISO in 1997.

French

Domaine(s)
  • Tiroir - Commission canadienne de sûreté nucléaire
  • Physique atomique
DEF

Produit de la décroissance radioactive; particule lourde émise par un noyau composé de deux protons et de deux neutrons et donc semblable au noyau de l'atome d'hélium.

CONT

La particule alpha, ou hélion, est une particule de charge positive +2, composée de deux protons et de deux neutrons : c'est le noyau de l'atome d'hélium. Elle est émise par les éléments «lourds» radioactifs, naturels ou artificiels. [...] Cette particule peut également être produite et accélérée [...] dans des accélérateurs de particules.

OBS

particule alpha : terme normalisé par l'ISO in 1997.

Record 2 - external organization data 2005-07-15

English

Subject field(s)
  • Atomic Physics
  • Compartment - Canadian Nuclear Safety Commission
CONT

An incident gamma ray reacts with an electron in an atomic orbit. The gamma photon gives all of its energy to the orbiting electron and ceases to exist. The electron is ejected from the atom and behaves like a beta particle. The ejected electron is called a photoelectron.

French

Domaine(s)
  • Physique atomique
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

Un rayon gamma incident heurte un électron sur une orbite atomique, il lui cède toute son énergie et cesse d'exister. L'électron est éjecté de l'atome et se comporte comme une particule bêta, on appelle cet électron éjecté photoélectron.
