National Preparedness: DHS and HHS Can Further Strengthen Coordination for Chemical, Biological, Radiological, and Nuclear Risk Assessments, Report to the Committee on Homeland Security and Governmental Affairs, U.S. Senate [open pdf - 641KB]
"The anthrax attacks of 2001 and more recent national reports have raised concerns that the United States is vulnerable to attacks with chemical, biological, radiological, and nuclear (CBRN) agents. Because of the potential consequences of such attacks, members of Congress have expressed the need for the Departments of Homeland Security (DHS) and Health and Human Services (HHS) to coordinate in assessing risks posed by CBRN agents. Government Accountability Office (GAO) was asked to examine how DHS and HHS coordinate on the development of CBRN risk assessments and the extent to which they have institutionalized such efforts. GAO examined relevant laws, presidential directives, collaboration best practices, and internal control standards; analyzed DHS and HHS CBRN risk assessments; and interviewed DHS and HHS officials."
