In July 2005, signatories to the CPPNM agreed to amend the Convention to address the risk of terrorism more effectively. The new measures that were introduced would make it more difficult for terrorists to cause a widespread release of radioactive material by attacking a nuclear power plant or detonating a radioactive dispersal device – commonly known as a dirty bomb.
2005年7月，CPPNM签署国同意修订该公约，以更有效地解决恐怖主义风险。所采取的新措施将使恐怖分子更加难以通过袭击核电站或引爆放射性装置——即常说的脏弹——大量释放放射性物质。
