Abstract

With the first version of the IDC^[*] software all known radionuclides, less the natural ones and one “naturalised” man-made one, caused a spectrum measured in the IMS* network to be characterised as interesting from a CTBT* point of view. But this is really not true for the majority of nuclides, so a change has been made to let only nuclides from a limited set of so called CTBT relevant nuclides have an impact on the characterization scheme. In the present paper the concept of CTBT relevance is analysed and a set of 96 relevant nuclides are defined. Out of these 51 are fission products and 41 are neutron activation products. There are also 4 nuclides which are residues from the nuclear fuel itself or added tracers.

Abstract

Die erste Version der IDC^[*] Software charakterisierte ein vom IMS Netzwerk gemessenes Spektrum als interessant in Hinblick auf den UVNV sofern es mindestens ein bekanntes Radionuklid enthielt, das nicht als natürliches oder als ein “natürlich” gewordenes anthropogenes Radionuklid gilt. Dies trifft jedoch auf die Mehrheit der Radionuklide nicht zu. Daher wurde eine Änderung vorgenommen, durch die nur eine begrenzte Anzahl von sogenannten UVNV-relevanten Nukliden das Charakterisierungsschema beeinflussen können. In der vorliegenden Arbeit wird das Konzept der UVNV-relevanten Nuklide analysiert und eine Gruppe von 96 relevanten Nukliden definiert. Diese besteht aus 51 Spaltprodukten sowie 41 Nukliden, die durch Aktivierung mit Neutronen entstehen. Hinzu kommen 4 Nuklide, die Rückstünde des Kernbrennstoffes oder hinzugefügte Spurenstoffe sind.
