This study focuses on the evaluation of radio xenon released following a Hiroshima-sized nuclear weapon explosion. Certain xenon isotopes, namely Xe135, Xe133m, Xe133 and The method consists of using radioactive evaluation data from Evaluated Nuclear Structure Data File (ENSDF). These data include the radioactive decay constant and half-life. Measurement data from real observations including Nevada underground nuclear test and Fukushima accident debris are also used. Appropriated calculation algorithms describing the radioactive evolution of the isotopes in consideration are used to evaluate the change over time of the radioxenon isotopic activity ratios. It appears that an isotopic activity of 1 million Tetra Becquerel (TBq) was reached by Xe135 two weeks after the explosion.
