Physical Protection Philosophy and Techniques in Brazil

There have been many discussions about the use of accountability measures to detect diversions of nuclear material. A number of states have established their own Safeguard Systems based on this concept. In recent years, a great deal of effort has been devoted to the development of a Security System to complement the Safeguard System based on accountability. This results from concerns arising out of the increasing frequency and severity of international terrorist activities and the growth of the nuclear industry around the world. The protective measures derived from this Security System would provide greater assurance against diversion. They would also protect the facilities and their components against illegal acts. Presently, a reliable Domestic Safeguards System is one that strikes a balance between the appropriate accountability and protective measures.
