The Role of of Xenon Isotopes Detectors for Nuclear Passive Defense

Xenon is one of the fission fragments which is produced in nuclear reactors and nuclear explosions with variety of its isotopes. With definition of special isotopes ratio of this element, we can specify the production base of these isotopes such as a nuclear explosion and leakage of a reactor or nuclear wastes. We can also determine the time of event occurrence. This paper describes the measurement of the variety of Xe isotopes; the production of spectrums associated with Xe different sources using the MCNP code, obtaining the activity and Xe different isotopes activity ratios and their sorting in oerder to determine the production source with neural network to design an early warning system.
