title = "Neutron activation analysis of geological and other environmental samples",
abstract = "By instrumental neutron activation analysis (INAA), using different irradiation and cooling times, it's possible to analyze over 40 elements in environmental samples. For some elements the detection limit is below 1 ppb and for some others some tens of ppm, being usually 0.1-1 ppm. The INAA is one of most reliable analytical method, because analysis is done directly from the sample; e.g. errors due to the impurities in chemical reagents are avoided. At the Reactor Laboratory, INAA has been used in a wide scale for analyses of different environmental samples. During the years 1983-1988 about 40 000 geological samples for the geochemical prospecting of metals have been analyzed, which means together about one million elemental determinations.",
