The Physical Protection of Nuclear Material and Nuclear Facilities, INFCIRC/225/Rev.4, provides recommendations for the physical protection of nuclear material against unauthorized removal during its use, storage and transport, whether domestic or international and whether for peaceful or military use, and provides recommendations for protection against sabotage of nuclear material or facilities. The recommendations contained in INFCIRC/225/Rev.4 detail the elements that should be included in a State's system of physical protection. They also recognize the potential proliferation concerns arising from the unauthorized removal of nuclear material and the potential adverse health and safety consequences resulting from the sabotage of nuclear material or facilities. Most industrialized and developing countries follow these recommendations in the establishment and operation of their physical protection systems.
