Experimental data of complex cluster radioactivity ({sup 14}C-{sup 34}Si) are systematically analyzed and investigated with different models. The half-lives of cluster radioactivity are well reproduced by a new formula between half-lives and decay energies and by a microscopic density-dependent cluster model with the renormalized M3Y nucleon-nucleon interaction. The formula can be considered as a natural extension of both the Geiger-Nuttall law and the Viola-Seaborg formula from simple {alpha} decay to complex cluster radioactivity where different kinds of clusters are emitted. It is useful for experimentalists to analyze the data of cluster radioactivity. A new linear relationship between the decay energy of cluster radioactivity and the number of {alpha} particles in the cluster is found where the increase of decay energy for an extra {alpha} particle is between 15 and 17 MeV. The possible physics behind this new linear relationship is discussed.
