The 1987 Version of the CEA radioactivity data bank is just distributed. It contains ENSDF data till September 1987, integral data from RUDSTAM when they improve ENSDF and for isotopes without experimental data, mean energies deduced from the gross beta theory. To assess this file we compare summation calculations with available experimental data at short cooling times the pulse integral measurements of Dickens and Akiyama, at several year cooling times specific experiments. The importance to have better knowledge of some nuclides like strontium and technetium isotopes are stressed.
