In nuclear decay process, internal conversion electron emission and electron capture leave vacancies in atomic shells. The vacancies in atomic shells give rise to rearrangements in the shells which are accompanied by the emission of X ray and the ejection of Auger electrons. The energies of X ray and Auger electron can be calculated on the basis of atomic electron binding energies in different atomic shells. The intensities of X ray and Auger electron can be also calculated from vacancy number, X ray fluorescence yield and vacancy transfer coefficient of different atomic shells. The calculation methods of energies and absolute intensities of X ray and Auger electron arising from nuclear decay are introduced briefly. The calculation codes and flow chart are presented. The application is also given by using some nuclear decays as an example.
