Description

The primary objective of the preparation of water and sewage sludge samples consists in reducing the volume of the sample aimed at increasing their activity concentration or specific activity, that means the radionuclide(s) to be determined are to be enriched in the sample in order to reduce the detection limit. As a rule, a simplified preparation procedure may be used, such as evaporation of water samples, drying of sludge samples, because the determination of nuclides by means of gamma spectroscopy is performed parallely and undisturbedly. It is also usual to combine different preparation procedures, e.g. to evaporate a water sample converting it into a measuring preparation in filter geometry for gamma spectroscopy, and further converting it into an yttrium-90 measuring preparation in order to determine strontium-90 via the daughter nuclide.

Abstract (German)

Primaeres Ziel einer Probenaufbereitung von Wasser- und Klaerschlammproben ist eine Volumenverminderung der Probe mit dem Ziel der Erhoehung der Aktivitaetskonzentration oder der spezifischen Aktivitaet, d.h. es soll eine Anreicherung des oder der zu bestimmenden Radionuklide in der Probe erreicht werden, um damit die Nachweisgrenze zu vermindern. In der Regel kann ein vereinfachtes Aufbereitungsverfahren wie z.B. Eindampfen von Wasserproben, Trocknen von Schlammproben, usw. angewendet werden, da die Bestimmung der Nuklide mittels Gammaspektrometrie ungestoert nebeneinander erfolgt. Es ist auch ueblich, verschiedene Aufbereitungs- bzw. Aufarbeitungsverfahren miteinander zu kombinieren, z.B. das Eindampfen einer Waasserprobe zu einem Messpraeparat in Filtergeometrie zur Gammaspektrometrie und Weiterverarbeitung zu einem Yttrium-90-Messpraeparat zur Bestimmung von Strontium-90 ueber das Tochternuklid.
