Das Projekt "Metrology for radiological early warning networks in Europe" wird/wurde gefördert durch: EURAMET e.V., European Association of National Metrology Institutes / Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Physikalisch-Technische Bundesanstalt.The aim of the project is to improve the metrological foundation of measurements (devices and methods) for monitoring airborne radioactivity and to introduce pan-European harmonisation in data reliability for area dose rate measurements which are input to the European Radiological Data Exchange Platform (EURDEP) and other monitoring networks. One of the main aims of this project is the fastest possible determination of a potential contamination at a kBq m-2 level. Metrologically sound methods will be developed for the evaluation of correct dose rate and activity concentration data. Appropriate harmonised calibration procedures for existing radiological early warning network stations in Europe will be systematically developed in the JRP for both dose rate and airborne radioactivity stations for the first time. Novel traceable reference materials and standard sources will be developed, and proficiency tests and other comparison exercises will be performed to quantify airborne radioactivity and dosimetry data at field stations. Monte Carlo simulations of detector responses and benchmark experiments will be used for the validation of new approaches in environmental radiation monitoring. Improved detection methods and data analyses techniques will be developed to enable accurate measurements of low activity concentrations of radon (in the range from 300 Bq/m3 and below) taking account of the fact that radon contributes to the background responses of many detector systems. Moreover, and as a pure scientific application, harmonised area dose rate data will allow investigations into parameters affecting climate change, e.g. soil moisture, using the Europe-wide dose rate mappings of EURDEP.

Das Projekt "Soil contamination: advanced integrated characterisation and time-lapse monitoring (SOILCAM)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Norwegian Institute for Agricultural and Environmental Research (Bioforsk).Objective: This project is aimed at improving current methods for monitoring contaminant distribution and biodegradation in the subsurface. Currently proven methods (based on invasive sampling of soil, soil water and gaseous phase) are unable to provide sufficiently accurate data with high enough resolution. Resulting in inability to assess of bioremediation progress and quantification of the processes involved in such bioremediation at field sites. Consequently, present assessment strategies to decide on optimal remediation approach, including design of monitoring systems, and evaluation of degradation progress, are severely flawed by uncertainty. Geophysical time-lapse measurements in combination with novel ground truthing methods give the possibility to determine: absolute contamination levels, spatial spreading, and reduced concentrations of contaminants in a heterogeneous environment. Geophysical methods of data acquisition alone are presently unable to provide absolute levels of biodegradable contamination concentrations. We aim to make improvements of fundamental constitutive relations between soil physical and degradation activity parameters and geophysically measurable parameters. Despite current improvements, there is a strong need to test these theories in practical field situations. Our project is dedicated to improving both site contamination assessment and the monitoring of bioremediation processes, and changes in soil environmental conditions. We suggest combining improved conventional soil monitoring techniques with state-of-the-art geophysical approaches. Partners in the project range from microbiologists to geophysicist, all with working experience from contaminated sites. Process studies involving lysimeters, and testing of the combination of technologies at two field sites are the major aims of the project. Focus on practical field situations and strong communication with stake-holders and SMEs will ensure high relevance for society.

Das Projekt "Erarbeitung fachlicher Grundlagen für die Entwicklung zeit- und kosteneffektiver Verfahren zur Bestimmung von Strahlenexpositionen durch Radon in Wohnungen" wird/wurde gefördert durch: Bundesministerium für Umwelt, Naturschutz und Reaktorsicherheit,Bundesamt für Strahlenschutz. Es wird/wurde ausgeführt durch: IAF Radioökologie GmbH.Im Rahmen des Vorhabens 'Erarbeitung fachlicher Grundlagen für die Entwicklung zeit- und kosteneffektiverVerfahren zur Bestimmung von Strahlenexpositionen durch Radon in Wohnungen(3607S04534)' wurde dargelegt, wie der Radonquellterm eines Hauses zusammen mit den Ergebnissen vonLuftwechselmessungen bestimmt bzw. modelliert werden kann und welche Prognosen daraus für ein möglichesRadonrisiko abgeleitet werden können. Die Auswertung von Lang- (mehrere Monate) und Kurzzeitmessungen(1 - 2 Wochen, zeitaufgelöst) zeigte, dass passive 2-Phasenmessungen (z. B. Tag/Nacht) in Wohnräumen sehr kostengünstig sind und eine Bewertung des Radonrisikos bzw. der individuellen Exposition derHausbewohner unter Berücksichtigung der Hausnutzung auf einer guten Grundlage ermöglichen.
According to the Directive 96/29/EURATOM the monitoring of occupational radiation exposures shall base on individual measurements carried out by an approved dosimetric service. Pursuant to the European Directive an approved dosimetric service is a body responsible for the calibration, reading or interpretation of individual monitoring devices …, whose capacity to act in this respect is recognized by the competent authorities. This concept will also be applied to radon services issuing passive radon measurement devices. Passive radon measurement devices1 using solid state nuclear track detectors or electrets are recommended for individual monitoring of exposures to radon. German regulations lay down that radon measuring devices are appropriate for purposes of occupational radiation monitoring if the devices are issued by recognized radon measurement services, and the measurement service submits devices of the same type issued for radon monitoring to regular intercomparisons conducted by the Bundesamt für Strahlenschutz (BfS). A radon measuring service is recognized by the competent authority if it proves its organisational and technical competence, e. g. by accreditation. These regulations have been introduced in the area of occupational radiation exposures. Nevertheless, it is recommended that radon measuring services which carry out radon measurements in other areas (e.g. dwellings) should subject themselves to these measures voluntarily. The interlaboratory comparisons comprise the organization, exposure, and evaluation of measurements of radon activity concentration or exposure to radon. The comparisons only concern radon-222; radon-220 is not in the scope. Radon services being interested can get further information from the European Information System on Proficiency Testing Schemes (EPTIS) and from the BfS websites.

Das Projekt "FP4-ENV 2C, STREAMER: Small Scale Structure Early Warning and Monitoring in Atmospheric Ozone and related exposure to UV-B Radiation" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Deutsches Zentrum für Luft- und Raumfahrt e.V. - Deutsches Fernerkundungsdatenzentrum.In recent years it has become evident that the distribution of ozone is strongly characterized by small scale structures both in time and space. This extraordinary variability is mostly due to the formation of finger-like structures ('streamers') reaching out from equatorial regions towards higher latitudes and obviously carrying ozone-low air towards densely populated areas such as Europe. As a consequence, strong modulations in the intensity of ground-level UV-B radiation is observed. Today, there is broad agreement that high UV dosages can cause considerable biological damage, to people, crops and animals. The objective of STREAMER (Small Scale Structure Early Warning and Monitoring in Atmospheric Ozone and Related Exposure to UV-B Radiation) is the development, installation and validation of an operational information and early warning system for providing daily nowcast and forecast of ozone vertical profiles, total column ozone and UV ground level intensity. Focus is on smaller scale structures such as streamers and mini-holes approaching Europe. STREAMER uses an end-to-end philosophy: it starts with the processing of the satellite's bits and bytes, continues with their interpretation into meaningful information and finally ends up with the provision of a comfortable on-line information system that allows customers easy access to exactly the kind of information they require. For the realization of the project's objectives a consortium was established within the 4th Framework Programme of the European Commission: German Aerospace Center (coordination), German Weather Service, Federal Environment Agency Austria, German Federal Environment Agency, Aristotle University Thessaloniki (Greece), Instituto Nacional de Technica Aerospatial (Spain), Federal Office for Radiation Protection (Germany). Customer oriented information transfer is realized by a comfortable, operational and easy-to-use on-line WWW-GIS system (World Wide Web - Geographical Information System). For more depth in data use, an Expert GIS system is being developed, enabling extensive statistical analysis.
