Abstract

A method for the determination of Sr-89/-90 in different types of environmental samples (German IMIS program) was to be adopted to the 2nd Saxon state laboratory for environmental radioactivity. Resulting from literature studies a combination of variable extraction steps for Y and Sr was chosen to be able for determining Sr-90 or Sr-89/-90 in a common as well as a rapid way. Measurements with a liquid-scintillation counter (LSC) and a low-background proportional counter (LBC) were performed after the same chemical separation steps in each case to find out the detector which is the best suitable one for our requirements. Different steps of the analytical procedure are discussed in detail and its characteristic parameters are given.

Abstract

Ein für Proben aus verschiedenen Umweltbereichen (IMIS-Programm) nutzbares Analysenverfahren für Sr-89/-90 sollte in der 2. Landesmessstelle für Umweltradioaktivität Sachsens eingeführt werden. Nach Literaturstudien wurde eine variierbare Kombination aus Y- und/ oder Sr-Extraktion gewählt, um Sr-90- oder Sr-89/-90-Bestimmungen sowie bei Bedarf deren Schnellbestimmungen durchführen zu können. Zur Auswahl des Messverfahrens wurden nach jeweils gemeinsamem chemischem Trennungsgang Messungen mit einem LSC und einem Low-Background-Proportionalzähler (LBC) durchgeführt. Verschiedene chemische Verfahrensschritte werden detailliert diskutiert und die Verfahrenskenndaten angegeben.
