Mr. Naseer highlighted the perception of radiological security threats, which varies between regional and international stakeholders. He said that it is crucial to recognize the shared global concern. While nuclear materials might be less accessible, the widespread use of radioactive sources in hospitals, research centers, and industries poses a significant risk. These civilian facilities, often considered soft targets, can be vulnerable to attacks or the theft of radiological materials.

He concluded his talk by addressing the multifaceted challenges posed by radiological security threats. He said the region has implemented various initiatives, including awareness-raising campaigns, security assessments, training programs, and regional cooperation. While these efforts have contributed to enhancing security and reducing the risk of illicit trafficking, a holistic approach is essential. This approach should consider not only technological solutions but also human factors, cultural nuances, and effective leadership.

The second speaker, Ms. Emily Adam,s presented an overview of the Office of Radiological Security (ORS) within the Department of Energy’s National Nuclear Security Administration.  She said that the ORS plays a crucial role in preventing high-activity radioactive materials from falling into the wrong hands. It focuses on four key radioisotopes due to their high activity and widespread availability: cobalt-60, iridium-192, americium-241, and cesium-137.

She emphasized that the potential consequences of radiological terrorism are severe, as even a small amount of these materials can cause significant contamination and long-term impacts. To mitigate these risks, the ORS employs a three-pronged strategy: protect, remove, and reduce.

She explained different ORS strategies. The ‘protect strategy’ involves enhancing the security of radioactive sources in use, ensuring their containment, and minimizing vulnerability to theft. This includes implementing security measures, providing training, and supporting response capabilities. The ‘remove strategy’ focuses on recovering and disposing of disused sources, reducing their potential for misuse. The ORS works with partners to safely remove and store these materials, both domestically and internationally. Lastly, the ‘reduce strategy’ aims to decrease global reliance on high-activity radioactive sources by promoting the adoption of non-radioisotope alternative technologies.

Ms. Adams concluded her presentation by emphasizing the ORS’s commitment to supporting research and development of alternative technologies and providing incentives for their adoption. Through the implementation of these strategies and robust collaboration with partners worldwide, the ORS is actively working to enhance global radiological security and prevent the misuse of radioactive materials for malicious purposes.

The webinar concluded with participants expressing their appreciation for the informative discussion, and the speakers encouraged further engagement in future webinars. The organizers emphasized the importance of continued participation and contributions from network members to sustain the momentum of the initiative.
