European CBRNE glossary

This European Standard contains terms and definitions applications to CBRNE.
Common understanding and communication is important in the implementation of an effective CBRNE response and this communication will be most effective if there is common understanding of the terms used. Many of the terms and definitions listed here have been widely used for many years, while others are the result of cross-cutting experience of areas of CBRNE. The gradual evolution of our understanding of CBRNE and response measures means that CBRNE terminology will continue to develop.

Europäisches CBRNE-Glossar

Diese Europäische Norm enthält Begriffe für CBRNE-Anwendungen.
Allgemeines Verständnis und Kommunikation sind wichtig bei der Umsetzung einer wirksamen CBRNE-Reaktion und diese Kommunikation wird am wirksamsten sein, wenn die verwendeten Begriffe allgemein verstanden werden. Viele der hierin aufgeführten Begriffe sind seit vielen Jahren sehr gebräuchlich, während andere das Ergebnis übergreifender Erfahrung über die verschiedenen CBRNE-Bereiche sind. Die schrittweise Entwicklung unseres Verständnisses hinsichtlich CBRNE und Gegenmaßnahmen bedeutet, dass sich die CBRNE Terminologie weiter entwickeln wird.

Glossaire CBRNE européen

La présente Norme européenne contient les termes et définitions applicables au domaine CBRNE.
Une compréhension et une communication communes sont importantes pour la mise en oeuvre d’une réponse efficace à un incident CBRNE, et cette communication sera d’autant plus efficace s’il y a une compréhension commune des termes utilisés. De nombreux termes et définitions répertoriés ici sont largement utilisés depuis de nombreuses années, alors que d’autres sont le résultat d’une expérience transversale dans le domaine CBRNE. L’évolution progressive de notre compréhension du CBRNE et des mesures de réponse signifie que la terminologie CBRNE va continuer à se développer.
