Behind the Index
The NTI Index is a unique public assessment of the status of nuclear materials security conditions in 176 countries.
Nuclear materials have the potential to unleash massive amounts of energy through a process called nuclear fission, and it only takes a small amount of plutonium or highly enriched uranium to build a bomb.
In developing the NTI Index, the EIU and NTI convened highly respected nuclear materials security experts from around the world. This group included experts who were from nuclear- and non-nuclear-weapon states and from developed and developing nations and who have a broad range of expertise.
