Since its launching in the mid-70s, thek0-standardization of NAA has been implemented and used in a growing number of laboratories worldwide. In the present paper, a survey is given of the situation in Europe, where the method or its associated subroutines are now operational in 22 industrial, governmental and university research centres spread over 12 countries plus IRMM of the European Union. In quite some of these places, not only practical applications are going on, but — as also reported here — further developments of the methodology are dealt with as well. These are related to such topics as the refinement of the fundamentals, the extension and improvement of the nuclear data library, the calibration of the Gedetector and of the neutron irradiation facility, the care for quality control/assurance and the upgrading of software for PC or mainframe.
