ETNA (Efficiency Transfer for Nuclide Activity measurements) is a new compu
ter program providing both detector efficiency transfer for various types o
f sources for coaxial source-detector geometries and coincidence summing co
rrections. This program, available for use on PCs, has a direct link to the
computerised database NUCLEIDE in order to automatically import the necess
ary radionuclide decay data. The specific features and facilities are outli
ned and examples are given. (C) 2000 Published by Elsevier Science Ltd. All
