We review the radioactive decay of nuclei via emission of α-particles using three different theoretical approaches. The half-lives of the radioactive nuclei, calculated using these three methods, are compared with each other and with available experimental data. The results show that the superasymmetric fission model with the double-folding procedure for obtaining the α-nucleus potential is the most reliable among the three models studied.
