Abstract

This work focuses on the determination of time zero nuclear events considering the Xe-135/I-135 isotopic activity ratio. Considered as relevant isotopes for CTBT, theses two radionuclides are usable for radioactive release timing. According the considered databases, some parameters namely A, U and F are evaluated taking into account the numerical difference between the radioactive values from nuclear database. We found that these parameters give different values by considering the databases ENDF 2011 and TENDL 2011. These proposed parameters can be used for a quick and accurate evaluation of the nuclear event time and its upper and lower age limits.

Keywords: Zero time, Isotopic activity ratio, Xe-135, I-135
