The Convention on the Physical Protection of Nuclear Material (INFCIRC/274) was signed at Vienna and at New York on March 3, 1980. It is "the only international legally binding undertaking in the area of physical protection of nuclear material. It establishes measures related to the prevention, detection and punishment of offenses relating to nuclear material." On July 8, 2005, an amendment was adopted that made it "legally binding for States Parties to protect nuclear facilities and material in peaceful domestic use, storage as well as transport. It also provides for expanded cooperation between and among States regarding rapid measures to locate and recover stolen or smuggled nuclear material, mitigate any radiological consequences of sabotage, and prevent and combat related offences." The amendment will be put into force after ratification by two-thirds of the Parties to the Convention.
