2 Piece of history George Hevesy and Hilde Levi, Denmark, 1936: „...The usual chemical methods of analysis fail, as is well known,for most of the rare earth Elements and have to be repleaced by spectroscopic, X- ray, and magnetic methods. The latter methods can be supplemented by the application of neutrons to analitical problems by making use of artificial radioactivity and of the great absorbing power of some of the rare earth elemnets for slow neutrons...” ENAA FNAA 1936-1944 nuclear reactors 1944-1950 sticintillation detectors 10 1950-1960 semiconductor detectors NaI(Tl) 100 1960-1970 semiconductor detectors Ge(Li) 1000 1970-2007 extensive applicatios 3000 INAA RNAA (CNAA) NAA PGNAA DGNAA Number of publications
