This proposal aims to close gaps that have been identified in nuclear and radiological preparedness following the first evaluation of the Fukushima disaster. It addresses the call Fission-2010-3.3.1: Update of emergency management and rehabilitation strategies and expertise in Europe. The consortium intends to review existing operational procedures in dealing with long lasting releases, address the cross border problematic in monitoring and safety of goods and will further develop still missing functionalities in decision support system ranging from improved source term estimation and dispersion modelling to the inclusion of hydrological pathways for European water bodies. As the management of the Fukushima event in Europe was far from being optimal, we propose to develop means on a scientific and operational basis to improve information collection, information exchange and the evaluation for such types of accidents. This will be achieved through a collaboration of industry, research and governmental organisations in Europe taking into account the networking activities carried out under the NERIS-TP project. Furthermore, the NERIS Platform member organisations (so far 43 partners) will be actively involved in the development.

The Institut de Radioprotection et de Sureté Nucléaire (IRSN) performed a series of 85Kr air sampling campaigns at mesoscale distances (18-50km) from the AREVA NC La Hague nuclear reprocessing plant (North West France) between 2007 and 2009. The samples were collected in order to test and optimise a technique to measure low krypton-85 (85Kr) air concentrations and to investigate the performance of three atmospheric dispersion models (RIMPUFF, HYSPLIT, and ADMS),This paper presents the 85Kr air concentrations measured at three sampling locations which varied from 2 to 8000Bqm-3, along with the 85Kr air concentrations output by the dispersion models. The dispersion models made reasonable estimates of the mean concentrations of 85Kr field measurements during steady wind conditions. In contrast, the models failed to accurately predict peaks in 85Kr air concentration during periods of rapid and large changes in wind speed and/or wind direction. At distances where we made the comparisons (18-50km), in all cases, the models underestimated the air concentration activities. © 2013 Elsevier Ltd.

The probability of homes in Ireland having high indoor radon concentrations is estimated on the basis of known in-house radon measurements averaged over 10km × 10km grid squares. The scope for using airborne gamma-ray spectrometer data for the Tralee-Castleisland area of county Kerry and county Cavan to predict the radon potential (RP) in two distinct areas of Ireland is evaluated in this study. Airborne data are compared statistically with in-house radon measurements in conjunction with geological and ground permeability data to establish linear regression models and produce radon potential maps. The best agreement between the percentage of dwellings exceeding the reference level (RL) for radon concentrations in Ireland (% > RL), estimated from indoor radon data, and modelled RP in the Tralee-Castleisland area is produced using models based on airborne gamma-ray spectrometry equivalent uranium (eU) and ground permeability data. Good agreement was obtained between the % > RL from indoor radon data and RP estimated from eU data in the Cavan area using terrain specific models. In both areas, RP maps derived from eU data are spatially more detailed than the published 10km grid map. The results show the potential for using airborne radiometric data for producing RP maps. © 2011 IOP Publishing Ltd.

The 129I content in precipitation, lake and river waters sampled in Ireland in 2005-2006 has been determined by accelerator mass spectrometry. In the case of lake and river waters, the data reveal little if any geographic dispersion with a mean (n = 14) concentration of 4.6 ± 1.2(1σ) × 108 atoms L-1. In contrast, concentrations of 129I in precipitation show significant variations both in time and space, with concentrations ranging from a low of 1.9 × 108 atoms L-1 to a high of 303 × 108 atoms L-1. These variations in precipitation are attributed to temporal changes in on-going discharges of 129I from west European reprocessing plants in conjunction with the trajectories of airstreams prevailing over Ireland at the time of sampling. © 2009 Elsevier B.V.

Long-term (circa 3 months) simultaneous measurements of indoor concentrations of thoron gas, airborne thoron progeny and radon were made using passive alpha track detectors in 205 dwellings in Ireland during the period 2007-09. Thoron progeny concentrations were measured using passive deposition monitors designed at the National Institute of Radiological Sciences (NIRS), Japan, whereas thoron gas concentrations were measured using Raduet detectors (Radosys, Budapest). Radon concentrations were measured in these dwellings by means of NRPB/SSI type alpha track radon detectors as normally used by the Radiological Protection Institute of Ireland (RPII). The concentration of thoron gas ranged from <1 to 174 Bq m-3 with an arithmetic mean (AM) of 22 Bq m-3. The concentration of radon gas ranged from 4 to 767 Bq m-3 with an AM of 75 Bq m-3. For radon, the estimated annual doses were 0.1 (min), 19.2 (max) and 1.9 (AM) mSv y-1. The concentration of thoron progeny ranged from <0.1 to 3.8 Bq m-3 [equilibrium equivalent thoron concentration (EETC)] with an AM of 0.47 Bq m&-3 (EETC). The corresponding estimated annual doses were 2.9 (max) and 0.35 (mean) mSv y-1. In 14 or 7% of the dwellings, the estimated doses from thoron progeny exceeded those from radon. © The Author 2011.

The increased discharge of Tc-99 from the Sellafield plant following the commissioning of the Enhance Actinide Removal Plant in 1994 was reflected in higher Tc-99 activity concentrations over much of the Irish Sea. The presence of this radionuclide in the marine environment is of concern not only because of its long half life but also high bio-concentration factor in commercially valuable species, such Norway lobster (Nephrops norvegicus) and common lobster (Homarus gammarus). Accurate predictions of the transport, and spatial and temporal distributions of Tc-99 in the Irish Sea have important environmental and commercial implications. In this study, transport of the Tc-99 material was simulated in order to develop an increased understanding of long-term horizontal and vertical distributions. In particular, impact of seasonal hydrodynamic features such as the summer stratification on the surface-to-bottom Tc-99 ratio was of interest. Also, material retention mechanisms within the western Irish Sea were explored and flushing rates under various release conditions and meteorological forcing were estimated. The results show that highest vertical gradients are observed between June and July in the deepest regions of the North Channel and the western Irish Sea where radionuclide-rich saline-poor water overlays radionuclide-poor saline-rich Atlantic water masses. Strong correlation between top-to-bottom ratio of Tc-99 and strength of stratification was found. Flushing studies demonstrate that as the stratification intensifies, residence times within the western Irish Sea increase. In stratified waters of the gyre Tc-99 material is flushed out from the upper layer much quicker than from the bottom zone. The research also shows that in the gyre the biologically active upper layers above the thermocline are likely to contain higher concentrations than the near-bed region. Long-term horizontal and vertical distributions as determined in this study provide a basis for assessment of a potential biota exposure to Tc-99. © 2010 Elsevier B.V.
