All the actinides are radioactive but Th232, U238, and to a lesser extent Pu244 and Cm247 are relatively stable.
FYI, of the lanthanides, La, Nd, Sm, Gd, Dy and Lu are likely to be naturally radioactive (of their radioactive isotopes, these have the longest
lived, >10^6 yr). My table here doesn't mention natural occurance of these isotopes.
