Join the movement to demand
secure the most dangerous
materials on earth.

In March 2016, leaders from around the world will gather in Washington, DC to improve policies that lock down dangerous nuclear materials. They must take bold action at this summit, since it could be a long time before the next international meeting of top leaders devoted to nuclear security.

You should care about effective nuclear security whether or not you support nuclear power. While only a handful of states possess nuclear weapons, over 700 nuclear power plants and research reactors exist or are being built, and radiological materials are used in research, industry and medicine on a daily basis. Nuclear technology affects everyone every day. If it is going to exist, it needs to be as safe and secure as possible.

As global threats and challenges have multiplied in the 21st century, our attention on securing nuclear materials can make a huge difference. All of us need to take action now and make our voices heard, because our leaders need a push in the right direction.

Join the 5 Priorities movement as we push for common-sense standards for securing nuclear materials. Speak up for actions that cut through the red tape and contribute to a safer future for everyone.

New Video: The Gap

On the eve of next week’s Nuclear Security Summit, we’re proud to present this video highlighting the gap between what needs to be done and what our leaders are doing.

Recent events have put the world’s focus back on the ongoing threat of terrorism—and with mounting evidence that groups like ISIS are trying to get radioactive materials to make a dirty bomb, it’s crucial that our leaders take full advantage of opportunities like next week’s summit to build a global nuclear security system.
