The 1990 Nuclear Data Sheets for A = 221 mass chain (1990Ak05) have been updated on the basis of the experimental results from various reaction and decay studies leading to nuclides in the A = 221 (Z = 85 to 92) since July 1990 (cutoff date of the last evaluation). The results obtained from various theoretical studies are given as comments. The updated level schemes and decay schemes, and experimental decay and reaction data on which they are based, are summarized and presented for all nuclides with mass number A = 221. The adopted values of level energies, level spins and parities are given, and {gamma}-ray energies, {gamma}-ray intensities, as well as other nuclear properties are presented. The references, J{pi} arguments, and necessary comments are given in the text. New measurements have been reported in Rn,Fr,Ra, and Ac and one new nuclide ({sup 221}U) has been given. All Q values have been adopted from 2003Au03.
