Using of the migration mechanism of the clusters, we can explain the phenomenon of the upward migration of parent nuclide and other metal particles. In reviewing the study of the domestic and foreign scholars who found the existence of the clusters of radon and its daughters, we studied the related properties of radon and its daughters by physical method. The results will help us revealing the characters of migration mechanism of the clusters of radon and its daughters observed by experiment. And it is the further evidence of the existences of the clusters of radon and its daughters.Firstly, in this paper we introduced the research on the existence of clusters of radon and its daughters by experiment, and we also introduced theoretical research methods of the clusters'related properties.Secondly, in this paper we employed first principles to study and analysis the special structures, stability and charged of the radon daughter clusters (lead-helium clusters). And this is the theoretical basic analysis of the upward migration mechanism of heavy metal particles and the reason why metal clusters charged.Again, we employed Modified Arrange Channel Quantum Mechanics (MACQM method for short) to calculate the ground state energy of helium clusters (radon-helium clusters) and radon and its daughters clusters (lead-helium clusters). MACQM provided a new method to calculate the ground energy of heavy metal ions and analyze the mechanism of upward migration.Finally, according to the own characteristics of radon and its daughters, combined with cluster theory, migration equation and numerical methods of radon and its daughters, we calculated average atomic numbers based on theoretical calculations on radon, and this can provide a theoretical basis for the possibility of the formation of radon and other lighter gas (helium).
