## Highlights

Concerns have grown that terrorists could use radioactive materials and sealed sources (materials sealed in a capsule) to build a "dirty bomb"-- a device using conventional explosives to disperse radioactive material. In 2003, GAO found weaknesses in the Nuclear Regulatory Commission's (NRC) radioactive materials licensing process and made recommendations for improvement. For this report, GAO assesses (1) the progress NRC has made in implementing the 2003 recommendations, (2) other steps NRC has taken to improve its ability to track radioactive materials, (3) Customs and Border Protection's (CBP) ability to detect radioactive materials at land ports of entry, and (4) CBP's ability to verify that such materials are appropriately licensed prior to entering the United States. To perform this work, GAO assessed documents and interviewed NRC and CBP officials in headquarters and in several field locations.
