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. See also Dirty bomb;
Nuclear, biological, chemical weapon.
