Uncertainties confronting stakeholders and decision-makers in planning intervention in urban and agricultural scenarios in the transition phase of a radiological emergency

This paper summarises the work undertaken under task 1 of work package 4 of the CONFIDENCE project. The objective was to investigate uncertainties confronting stakeholders and decision makers at the transition phase of an accident and to frame the scene for subsequent tasks to investigate how stakeholders respond to that uncertainty. Urban and agricultural scenarios were considered separately. For urban scenarios, the investigation focussed on uncertainties in model predictions of residual dose from external exposure to radionuclides deposited in the urban environment. For agricultural scenarios, the objective was to analyse the uncertainties in the transfer and fate of radionuclides along different components of agricultural systems and their response to recovery actions.
