Glossary Header-left2.png

The ICRP Glossary collects ICRP’s definitive explanations of terms for current use. Some entries include historical descriptions to help readers better understand the term in a particular context.

It is a living document, updated regularly.

Many ICRP publications feature their own glossaries including, for example, highly specialized terms relevant to that specific publication or helpful for a reader to have close at hand, or when introducing new terms to be added to the ICRP Glossary.

Although the ICRP Glossary is not a dictionary, terms already well covered in the Oxford English Dictionary are not included here unless further explanation is needed to understand the way in which these terms are used in ICRP publications.
