SAFETY AND SECURITY FOR RADIOACTIVE SOURCES WITHIN THE
UNITED STATES

The events of September 11, 2001, heightened concerns about the use of risk-significant
radioactive materials in a malevolent act within the United States. Such an event is of particular
concern because of the widespread use of radioactive materials (often contained in sealed
sources) in the United States by industrial, medical, and academic institutions. The theft or
diversion of such materials, in risk-significant quantities, could lead to their use in a malicious
act. A significant culture change occurred at the U.S. Nuclear Regulatory Commission (NRC)
and for the regulated community, to have to consider the potential for malevolent unauthorized
access to licensed radioactive materials. This challenge was significant because safety and
security professionals spoke “different languages” and have different constraints on their work.
Security professionals want to control the flow of information; safety professionals see the need
to share information. The presentation will provide an overview of how the NRC ensures the
safety and security of Category 1 and 2 radioactive materials within the United States.
