Summary: | Motivated by simplifying the calculation process of radioxenon isotopic activity used by scientist community in nuclear event characterization, the analytical formulas of the numbers of nuclides and isotopic activities of CTBT relevant radioxenon Xe-135, Xe-133m, Xe-133 and Xe-131m proposed in this work can be useful and incorporated in the calculation algorithms for nuclear event studies. The calculated ages using analytical formulas and radioxenon activity data from real observations compare well with the reported ages and show good results of event timing precision.
•Systems of differential equations describing the decay of the CTBT-relevant radioxenons are solved analytically;•Analytical formulas of the number of nuclides for Xe-135, Xe-133m, Xe-133 and Xe-131m under in-growth condition are given;•For validation, the analytical solution results are used in comparison with numerical solutions given by other authors;•The calculated ages using radioxenon activity data from real observations are in accordance with the reported ages. |
