Recommendations on the effectiveness of sheltering as a protective action in the UK Open
To mitigate exposure of the public during an accidental atmospheric release of radioactive material, protective actions may be implemented. Sheltering can have a protective effect against both external and inhalation exposure pathways. Thi…

Summary and recommendations from the workshop ‘Integrating measurements and atmospheric-dispersion modelling to enhance the UK response to radiological atmospheric releases’ Open
Effective preparedness and response to an atmospheric release following a radiological incident relies on information concerning the source, transport and eventual removal of the contaminant. A notable improvement to emergency preparedness…

Ranking uncertainties in atmospheric dispersion modelling following the accidental release of radioactive material Open
During the pre-release and early phase of an accidental release of radionuclides into the atmosphere there are few or no measurements, and dispersion models are used to assess the consequences and assist in determining appropriate counterm…

Uncertainty propagation in atmospheric dispersion models for radiological emergencies in the pre- and early release phase: summary of case studies Open
In the framework of the European project CONFIDENCE, Work Package 1 (WP1) focused on the uncertainties in the pre- and early phase of a radiological emergency, when environmental observations are not available and the assessment of the env…

Operationalising an ensemble approach in the description of uncertainty in atmospheric dispersion modelling and an emergency response Open
Uncertainties were propagated through the chain of atmospheric dispersion and radiological assessment models based on an ensemble approach for a range of scenarios. It was apparent that the time taken to complete model runs, ranging from s…

CONFIDENCE dissemination meeting: Summary on the scenario-based workshop Open
The CONFIDENCE dissemination workshop “Coping with uncertainties for improved modelling and decision making in nuclear emergencies” was held in December 2–5, 2019 (Bratislava, Slovak Republic). About 90 scientists and decision makers atten…

Take one dispersing plume and add some precipitation: using ensembles to simulate deposition uncertainty Open
<p>In the event of an accidental airborne release of radioactive material, dispersion models would be used to simulate the spread of the pollutant in the atmosphere and its subsequent deposition. Typically, meteorological information…
