Chemical, Biological, Radiological, Nuclear (CBRN) Weapon
Definition
Chemical, Biological, Radiological, Nuclear (CBRN) Weapon — a less commonly used phrase with essentially the same meaning as "nuclear,
biological, chemical (NBC) weapon." 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.
