The multiconfiguration Dirac-Hartree-Fock (MCDHF) model has been employed to calculate the transition rates between the nine lowest levels of radium. The dominant rates were then used to evaluate the radiative lifetimes. The decay of the metastable 7s7p3P0 state through 2-photon E1M1 and hyperfine induced channels is also studied.
