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 nuclear reactors sticintillation detectors semiconductor detectors NaI(Tl) semiconductor detectors Ge(Li) extensive applicatios 3000 INAA RNAA (CNAA) NAA PGNAA DGNAA Number of publications
