Record 1 2014-10-30

English

Subject field(s)
  • Atomic Physics
DEF

[The emission of] electrons or positrons with penetrating power varying with the energy of the particle.

OBS

[These particles] present an internal exposure hazard and higher-energy beta particles may also be an external exposure hazard. Beta emitters are frequently found in medical or research environments.

French

Domaine(s)
  • Physique atomique
DEF

[Émission d’électrons] ou positrons dont le pouvoir de pénétration varie selon l'énergie de la particule.

OBS

Ce type de rayonnement présente un risque d'exposition interne, et les particules bêta de haute énergie présentent également un risque d'exposition externe. Les émetteurs bêta sont fréquents dans le milieu médical ou en recherche.

Key term(s)
  • rayonnement beta

Record 2 - external organization data 2011-10-27

English

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

Ionizing radiation consisting of a stream of beta particles emitted by radioactive substances at high velocity.

CONT

In beta radiation the rays travel distances of up to a few millimeters in human soft tissues before they are fully absorbed.

CONT

Beta radiation consists of fast moving electrons ejected from the nuclei of atoms. More penetrating than alpha radiation, beta radiation can pass through up to two centimetres of water or human flesh, but is stopped by a sheet of ordinary window glass.

Key term(s)
  • β radiation
  • β rays
  • β ray
  • beta ray

French

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

Particules atomiques très mobiles et peu pénétrantes.

CONT

Les rayons bêta sont émis par les électrons éjectés du noyau des atomes et se déplacent rapidement. Ils sont plus pénétrant que les rayons alpha et peuvent traverser 1 ou 2 centimètres d'eau ou de chair, mais pas une vitre ordinaire.

OBS

On les utilise souvent en médecine ou en recherche.

Key term(s)
  • rayonnement β
  • rayons β
  • rayon β
  • rayon bêta

Spanish

Campo(s) temático(s)
  • Física atómica
  • Compartimiento - Comisión Canadiense de Seguridad Nuclear
