Description
The paper reviews the available, fundamental measuring methods relying on γ-spectroscopy for their possible application in whole-body and partial-body counters for detection of manifold incorporation of radionuclides. Particular emphasis is placed on the response functions of various detectors, the assembly, the differentiated radioactivity distribution in the body, the various components of background activity and the corresponding suppression mechanisms, and possible ways of using the energy dependence for optimised detection of specific γ energies in a given body region. Criteria and relations as well as their advantages and drawbacks are discussed. (orig./CB)
Abstract (German)
Diese Arbeit prueft die zur Verfuegung stehenden grundlegenden, γ-spektroskopischen Messmethoden auf deren moegliche Anwendung im Spektrum der Ganz- und Teilkoerperzaehler zum Nachweis der mannigfach inkorporierten Radionuklide. Insbesondere wird eingegangen auf die Response Funktionen verschiedener Detektoren, die Anordnung, die differenzierte Aktivitaetsverteilung im Koerper, die verschiedenen Untergrundkomponenten und deren Unterdrueckungsmechanismen sowie die Beeinflussung durch die Energieabhaengigkeit zum optimalen Nachweis spezifischer γ-Energien an einem bestimmten Ort am Koerper. Kriterien und Relationen sowie deren Vor- und Nachteile werden diskutiert. (orig.)
