Record 1 2010-11-26

English

Subject field(s)
  • Atomic Physics
DEF

The energy released from an atom in the form of neutral particles called neutrons.

OBS

Neutrons are part of the basic building blocks of atoms. They have no charge and are about the same mass as a proton. Due to ion-producing collisions with matter and absorption/decay processes, neutrons are a type of ionizing radiation.

French

Domaine(s)
  • Physique atomique
DEF

Propagation d’énergie atomique, sous forme de particules neutres appelées neutrons.

Record 2 2003-10-15

English

Subject field(s)
  • CBRNE Weapons
CONT

Neutron weapons are designed for the destruction of living organisms; they are not designed for the destruction of building and technical facilities.

CONT

Neutron weapons are miniature thermonuclear weapons with a calibre of about 1 kt [kiloton] (at most up to 15 kt), where a fissioning initiator triggers the thermonuclear synthesis of tritium and deuterium. In the course of this synthesis, as much as 80% of energy is released in the form of immediate penetrating neutron radiation with high energy. Thus, the neutron weapon is referred to as a weapon with amplified radiation.

OBS

enhanced radiation weapon; ERW: term and abbreviation extracted from the "Disarmament and Peace Keeping" glossary with the permission of the United Nations Office at Geneva.

Key term(s)
  • reinforced radiation effect weapon
  • reinforced neutron radiation weapon

French

Domaine(s)
  • Armes CBRNE
CONT

L'arme à neutrons, dite aussi à rayonnement renforcé, est tout à fait particulière en ce que, théoriquement, elle ne produit que des effets mortels pour les humains, sans entraîner de dommages aux matériels.

OBS

arme neutronique : terme tiré du lexique «Désarmement et Maintien de la Paix» avec l'autorisation de l'Office des Nations Unies à Genève.

Spanish

Campo(s) temático(s)
  • Armas QBRNE
CONT

Sam Cohen teorizó que si a una bomba de hidrógeno se le quitaba la carcasa de uranio, ésta emitiría una gran cantidad de neutrones, que podrían viajar grandes distancias, atravesar estructuras blindadas y matar o incapacitar a quienes estuvieran dentro de ellas. Además, como la radiación remanente se produce principalmente por la fisión nuclear, dijo que dado que sólo quedaría una pequeña masa fisionable en el núcleo de la bomba, los residuos serían sólo de una fracción que el de una bomba atómica convencional, pero mucho más letal. Así nació el Arma de Radiación Potenciada (Enhanced Radiation Weapon) [...]

Record 4 - external organization data 1994-10-07

English

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

penetrating atomic particles that result from collisions between cosmic rays and atoms in the atmosphere, and from some specialized man-made sources. This type of radiation is often used in portable nuclear gauges.

CONT

Neutron radiation is produced by the fission process in nuclear reactors. It is the form of radiation which can cause other materials to become radioactive. This property is used to create radioisotopes for medicine and industry. Water and concrete are used as a shield against neutron radiation from the reactor core.

Key term(s)
  • neutrons

French

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

particules atomiques pénétrantes résultant, soit de la collision entre les rayons cosmiques et les atomes de l'atmosphère, soit de certaines sources artificielles spéciales. Ils sont souvent utilisés dans les jauges nucléaires portatives.

CONT

Les neutrons peuvent aussi être très pénétrants. Ils sont produits par la fission dans les réacteurs nucléaires. Comme ils peuvent rendre d'autres matières radioactives, on les utilise pour préparer des radio-isotopes destinés à des applications médicales et industrielles. L'eau et le béton peuvent servir de bouclier efficace contre les neutrons qui proviennent du noyau des réacteurs.
