Radioactive cluster decays are studied in different nuclear regions. It is found that the decay of protons and alpha particles can be well described by the Gamow two-step mechanism of first formation and then penetration of the particle through the Coulomb Barrier. The same mechanism is found to be apt to describe the decay of heavy clusters. Formation amplitudes of proton, alpha and heavy clusters are calculated. The decay widths of all possible fragments lighter than 48Ca emitted from all possible mother nuclei with know masses are also calculated and the mos likely decaying clusters are presented.
