"A Call for German Leadership in Combating Nuclear Terrorism"
Op-Ed
By Rolf Mowatt-Larssen, Senior Fellow, Belfer Center for Science and International Affairs and Tom Bielefeld, Associate, Project on Managing the Atom
"...Germany has an opportunity at the Washington summit — and thereafter — to step up and lend non-American leadership to the problem. Recognizing that in many of the world's capitals the threat of nuclear terrorism is not yet being taken seriously, and when in some of them the very notion is even considered an American pretext for an entirely different, potentially hostile political agenda, non-American leadership is most urgently needed."

"Nuclear Forensics and Its Role in Security Policy"
Presentation
By Tom Bielefeld, Associate, Project on Managing the Atom
Nuclear forensic analysis is currently discussed as a potentially important new tool to prevent nuclear terrorism by enabling investigators to attribute nuclear materials to their production facility and thus deterring potential state actors from transferring such materials to terrorists. In the seminar, an introduction into the technical possibilities and limitations of pre- and post-attack nuclear forensics will be given, based entirely on open source analysis. This will be followed by a discussion about the roles that nuclear attribution can — or cannot — play in security policy.

"The Security of Medical and Industrial Radioactive Sources"
Conference Paper
By Tom Bielefeld, Associate, Project on Managing the Atom and Helmut W. Fischer
Recent foiled and successful terrorist plots in Europe and the US (including two cases in the UK and Germany which included plans to design radiological dispersal devices in 2004 and 2005), clearly demonstrate that domestic or locally acting terrorist cells have become an important part of the terrorist threat picture. The uncovered “dirty bomb” – plots involved radioactive material of type or quantity that would not have caused much damage. Still, these observations underscore the necessity to revisit the issue of radioactive sources security in countries which may become the target of a radiological attack. This includes in particular countries in Europe, many of which in the past relied on sophisticated — but safety centred — regulations and functioning oversight institutions.

"Reducing Nuclear and Radiological Terrorism Threats"
Conference Paper
By Matthew Bunn, Associate Professor of Public Policy; Co-Principal Investigator, Project on Managing the Atom and Tom Bielefeld, Associate, Project on Managing the Atom
Urgent actions are needed to prevent a nuclear or radiological 9/11. Terrorists are actively seeking nuclear weapons and Radiological Dispersal Devices (RDDs) and the materials to make them. There are scores of sites where the essential ingredients of nuclear weapons exist, in dozens of countries worldwide. There are thousands of sites worldwide where radiological materials exist. Many of these sites are not sufficiently secured to defeat the kinds of threats that terrorists and criminals have demonstrated they can pose. A dangerous gap remains between the urgency of the threat of nuclear and radiological terrorism and the scope and pace of the U.S. and world response. While the gap has narrowed significantly in recent years, much more needs to be done. This paper describes the nuclear and radiological terrorism threats, analyzes the actions taken so far to address these threats, and recommends further actions going forward.

"Security and Damage Potential of Commercial Radioactive Sources"
Journal Article, Journal of Nuclear Materials Management, issue 3, volume 35
By Tom Bielefeld, Associate, Project on Managing the Atom and Helmut W. Fischer
MTA/ISP fellow Tom Bielefeld and his co-author Helmut Fischer focus on the problem of protecting radiological sources, preventing a “dirty bomb” attack, and putting measures in place to mitigate the effects should an attack occur.

"85Kr in Industrial Krypton Gas: Origin, Identification and Dosimetry"
Conference Paper
By Helmut W. Fischer, Bernd Hettwig and Tom Bielefeld, Associate, Project on Managing the Atom
Helmut W. Fischer, Bernd Hettwig, and Tom Bielefeld presented "85Kr in Industrial Krypton Gas: Origin, Identification and Dosimetry" at the Third European IRPA Congress in June 2010. They reported on a case of transcontinental transport of krypton gas, triggering of a radiation alarm and subsequent in situ measurement by different radiometric techniques.
