Radiological dispersal devices

The Defense Science Board Summer Study report recognizes a "new and ominous trend transnational threat with a proclivity towards much greater levels of violence." The report states that transnational groups have both access to, as well as the motivation to use, weapons of mass destruction (WMD). Military and civil defense planners are increasingly concerned about possible state and non-state use of radiological dispersal devices (RDD) against U.S. forces and population centers abroad and at home.
