Metrology for mobile detection of ionising radiation following a nuclear or radiological incident — •Patrick Kessler, Harald Dombrowski, and Stefan Neumaier — Physikalisch-Technische Bundesanstalt, Braunschweig, Deutschland

The European project ''prepardness'' focuses on the protection of the public against ionising radiation and radioactive contaminations caused by nuclear or other radiological incidents. During and following such an accident radiation protection authorities and other decision makers need quick and credible information on contaminated areas. To provide such data, accurate and traceable methods for measuring activity concentrations of radioactive contaminations and dose rates need to be developed, as well as transportable air-sampling systems and aerial detection systems for remote measurements.

These requirements are met by four different work-packages. Firstly, the development of unmanned aerial detection systems for the early monitoring of areas affected. Secondly, transportable air-sampling systems, because the average distance between field stations in Europe is up to hundreds of km and therefore the data is not representative for localised nuclear or radiological incidents. Thirdly, the data from civilian radiation measurement networks which are now more and more commonly available. The density and mobility of these networks might support decision makers, however the quality of the data has to be investigated. Fourthly, for the long term monitoring of affected areas, the passive dosimetry for environmental radiation monitoring requires the harmonisation of measurement and data acquisition procedures.
