The ICRP Glossary collects ICRP’s definitive explanations of terms for current use. It is a living document, updated regularly. Each entry shows the date it was last updated, and some include past glossary entries to help readers better understand the term in a particular context.
Many ICRP publications have included their own glossaries. The ICRP Glossary includes most of the terms in these other glossaries, many with updated entries. ICRP publications will continue to have their own glossaries when necessary, for example for highly specialized terms relevant to a single publication or helpful for a reader to have close at hand, or when introducing a new term which would also 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.
The ICRP Glossary shown here comprises some 400 terms. Entries for an additional approximately 400 terms are being prepared, and will be added here in due course.
