Abstract: The parameters of the emission Mössbauer spectra of PbTe using the $^{119m}$Sn daughter isotope with different parent nuclei $^{119mm}$Sn, $^{119m}$Sb, and $^{119m}$Te are compared. This comparison makes it possible to identify impurity tin atoms in both lead-telluride sublattices. It is found that the ratio of tin concentrations in different sublattices depends on the time after source preparation.
