(CNN) -- The terrorist threat posed by radicalized Muslim- Americans has been exaggerated, according to a study released Wednesday by researchers at Duke University and the University of North Carolina at Chapel Hill.

It compiled a list of 139 individuals it categorized as "Muslim-American terrorism offenders" who had become radicalized in the U.S. in that time -- a rate of 17 per year.
That level is "small compared to other violent crime in America, but not insignificant," according to the study, titled "Anti-Terror Lessons of Muslim-Americans." (MORE)
