Harnessing monitoring measurements in urban environments for decision making after nuclear accidents

Abstract
This article gives an overview on the conceptual design of the Inhabited Areas Monitoring Module IAMM which will be introduced into European decision support systems for nuclear emergencies. It will improve the use of monitoring data of radioactive contamination in urban environments for decision making. IAMM converts the dated gamma dose rate (GDR) measurements from geo-referenced locations into maps of surface contamination with an enhanced spatial resolution. Depending on the availability of the monitoring data, IAMM relies on two modes of operation. If there are only a few measurements, these are taken to improve the maps from a deposition model using data assimilation. If the number of measurements is sufficient to apply spatial interpolation IAMM will rely entirely on monitoring data. Suitable geo-referenced data points will be interpreted by IAMM with respect to their detector environment using the concept of location factors. The endpoints of IAMM can be used directly for decision making or dose calculations with either simple dose models or the more refined EuRopean Model for INhabited areas (ERMIN).
Kurzfassung
Dieser Beitrag gibt einen Überblick über das Entwurfskonzept des Inhabited Areas Monitoring Module (IAMM), das in europäischen Entscheidungshilfesystemen für nuklearen Notfallschutz eingesetzt werden soll. Das Modul wird die Verwertung von Überwachungsdaten zur radioaktiven Kontamination in städtischer Umgebung für die Entscheidungsfindung verbessern. IAMM überführt datierte Messungen der Ortsdosisleistung an georeferenzierten Orten in Karten der Oberflächenkontamination mit hoher räumlicher Auflösung. Abhängig von der Verfügbarkeit der Überwachungsdaten besitzt IAMM zwei verschiedene Arbeitsmoden. Gibt es nur wenige Messungen, werden diese mit Hilfe der Datenassimilation zur Verbesserung von Karten aus einem Depositionsmodell genutzt. Bei einer ausreichenden Anzahl von Messungen können räumliche Interpolationsverfahren ausschließlich mit Überwachungsdaten angewandt werden. Passende georeferenzierte Datenpunkte werden im Hinblick auf ihre Detektorumgebung interpretiert, gestützt auf das Konzept der Umgebungsfaktoren. Die Endpunkte von IAMM können direkt zur Entscheidungshilfe genutzt werden oder für Dosisberechnungen. Dabei werden einfache Dosismodelle oder auch das fortgeschrittene EuRopean Model for INhabited areas (ERMIN) angewandt.
