Nuclear spectroscopic information for known nuclides of mass number 218 (Bi,Po,At,Rn,Fr,Ra,Ac,Th,Pa,U) with Z = 83 to 92 and N = 135 to 126 have been evaluated and presented together with adopted energies and J{pi} of levels in these nuclei. No excited state data are yet available for {sup 218}Bi, {sup 218}At and {sup 218}Pa. Octupole structures are known in {sup 218}Rn, {sup 218}Fr, {sup 218}Ra and {sup 218}Ac nuclides. Since the previous update (1995El08) about ten years ago, many new data are available e.g. decays of {sup 218}Bi to {sup 218}Po, {sup 222}Ra to {sup 218}Rn and {sup 222}Th to {sup 218}Ra; high-spin structures in {sup 218}Rn and {sup 218}Fr; and lifetimes of excited states in {sup 218}Ra. This evaluation supersedes previous full evaluations of A = 218 published by 1987El12 and 1977To13; and an interim evaluation published in 'update' mode by 1995El08 with literature cutoff date of August 1995.
