ACCIDENTAL URBAN CONTAMINATION
The Workshop on Consequences of Accidental Contamination of the Urban Environment'', June 9--12, 1987, Roskilde, Denmark, was organised jointly by the Radiation Protection Programme of the Commission of the European Communities and the Riso National Laboratory. Methodologies for evaluating the off-site radiological consequences of hypothetical accidental atmospheric releases of radioactivity are applied in most countries involved in the nuclear fuel cycle. However, over the last decade there has been a considerable evolution in this field and there is now an increasing interest in what is called Probabilistic Risk Assessment''. These probabilistic accident consequence assessment models are used to evaluate the risks presented by accidents in nuclear installations and to provide inputs into decisions on siting, emergency planning and alternative design options. Their use in quantitative decision making framework has implications both for the reliability or precision of the model predictions and for the range of situations for which the models are applicable. In 1983, the Radiation Protection Research Programme initiated a two-year project on Methods for Assessing the Radiological Impact of Accidents (MARIA)'' and this project is now continued in the frame of the 1985--1989 programme. Key contractors are KfK from the Federal Republic of Germany and NRPB from the United Kingdom. All major European institutions active in this field also collaborate in a total of 18 contracts. The purpose is to elaborate, by the end of 1989, a generic probabilistic methodology for the evaluation of potential consequences of accidental releases of radioactivity into the environment. Areas for which major uncertainties exist for assessing the consequences of an accident especially concern the urban agglomerations. Indeed, these are characterised by high population densities and consequently contribute substantially to the collective dose commitment. This Workshop succeeded in accomplishing the following objectives: - to draw up the state-of-the-art of the implications of an accidental contamination of the urban environment; - to lay down the scientific bases for cost-effective countermeasures and decontamination procedures in the urban environment; - to trigger further experimental work in view of reducing the inherent uncertainties.
