chemical, biological, radiological, nuclear weapon (CBRN)
Chemical, biological, radiological, nuclear (CBRN) weapon is a less commonly used phrase with essentially the same meaning as "nuclear, biological, chemical (NBC) weapon."
Additional Information
This phrase is probably more technically correct because dirty bombs are not truly nuclear weapons but, rather, radiological weapons. Nevertheless, dirty bombs are considered one of the NBC perils that insurers typically seek to exclude in the commercial lines policies they write.
