Nuclear Security and Terrorism

Information for Journalists and Interested Citizens

Nuclear technologies, fissile materials, and radioactive sources are at risk to be targeted by criminals and terrorists. This is not an alarmist statement, but a real concern.

Here are some facts about nuclear crime and terrorism:

  • Radioactive materials, widely used in medicine, industry, and research, have recurrently been weaponized to injure, maim, and murder people.

  • Nuclear power plants were attacked, sabotaged, or credibly threatened, with dozens of serious incidents publicly documented in the past forty years.

  • Two major terrorist organizations, Aum Shinrikyo and al-Qaeda, seriously pursued parts and materials to make atomic bombs. Al-Qaeda presumably even experimented with essential – but non-nuclear – mechanisms for such a device.


The good news is that terrorists have not been successful yet in causing large-scale radioactive contamination - or mounting a nuclear attack (obviously). But to keep it that way, governments, industry, and academia must keep strengthening nuclear security instruments and practices - most urgently those to protect nuclear weapons-usable fissile materials from theft and nuclear facilities from attack or sabotage.

The articles on this website introduce some of the key concepts of nuclear security and nuclear terrorism prevention. They explain what needs to be done to keep highly enriched uranium and plutonium, the main ingredients of nuclear weapons, out of the hands of terrorists. They discuss the terrorist threat to nuclear facilities, including some of the lessons to be learned from the Fukushima disaster for both safety and security of nuclear power plants. And they deal with the issue of “dirty bombs” and how to protect the radioactive sources used in medicine and industry.

The collection includes links to open-access papers and presentations written by some of my great colleagues, by other trusted experts, and by myself. I hope that it will be useful as a backgrounder for journalists and for everybody else who is interested in learning about these important matters.

Note that this site and its subpages are currently under (re)construction.
