—Methods of detecting and locating nuclear radioactive targets via wireless sensor networks (WSN) are proposed in this paper. In real applications, a nuclear radioactive target can be interpreted either as a hidden nuclear weapon held by nuclear terrorists or as a leak of nuclear radioactive materials at a unit of nuclear power stations. Assume a WSN is composed of radiation detectors deployed ...

The emergence of nuclear weapons as a new actor in international relations has introduced a new area in the international security arena. Since the appearance of these weapons, there have been increasing efforts to limit and destroy them in order to achieve global peace in the framework of disarmament and centered around the Treaty on the Non-Proliferation of Nuclear Weapons. Along with the eme...

When does a state become a ‘‘nuclear weapon state’’? How we choose to answer this question has significant implications for proliferation assessment, analysis, and policy. Traditionally, the standard demarcation line has been a state’s first nuclear test, but in recent years analysts have increasingly focused instead on the accumulation of a significant quantity (SQ) of fissile material. The ar...

India is building a 500 MWe Prototype Fast Breeder Reactor, which is scheduled to be operational by 2010. India has refused to accept international safeguards on this facility, raising concerns that the plutonium produced in its uranium blankets might be used to make nuclear weapons. Based on neutronics calculations for a detailed threedimensional model of the reactor, we estimate that up to 14...

Since decision making in the face of emotionally laden problems and incomplete information is very difficult, it is useful to develop and test alternative decision methodologies and/or criteria. One approach is to enlarge the system in which the decision is to be made, for example, go from a national system to an international one, as well as to alter the decision criteria. This paper is a heur...

Radiocaesium isotopes are among the long-lived radionuclides which were released in largest quantities into the environment as a consequence of the atmospheric nuclear weapon tests and accidents involving nuclear material (Chernobyl and Fukushima, etc.). Its transfer to plants, especially those for human or animal food, can be a major pathway for human intake and, therefore, have a significant ...
