“…Radioactive contaminants in groundwater can originate from geological deposits of radionuclides but also can originate from anthropogenic sources, such as wastes from nuclear power plants, nuclear weapons testing, and improper disposal of medical radioisotopes (Dahlgaard et al 2004 ; Lytle et al 2014 ; Huang et al 2012 ). Radioactive substances can enter the human body through a variety of routes, including drinking water.…”

“…The most frequently used treatment techniques include micro-ultrafiltration using ceramic filters, reverse osmosis and selective sorption on organic and inorganic materials [4]. For example, a relatively successful method employed in the LRW cooling pool at the Taiwan Research Reactor uses a cascade of ceramic filters with diatomite [5]. However, equivalent technology cannot be applied on highly mineralized LRW, which is the case for the LRW from BN-350.…”

The use of composite materials based on metal ferrocyanides combined with natural mineral sorbents for treatment of high salinity Cs-containing liquid radioactive waste (LRW) was investigated. The study indicated that among the investigated composites, the best sorption characteristics for Cs were shown by materials based on copper ferrocyanide. Several factors affecting the removal of cesium from LRW, namely total salt content, pH and organic matter content, were also investigated. High concentrations of complexing organic matter significantly reduced the sorption capacity of ferrocyanide sorbents

“…Processes & Impacts PAPER digestion followed by ICP-MS or ICP-OES analysis have been used; [12][13][14][15] these methods, however, result in radioactive material being lost to the atmosphere and sewerage as waste. Thus, nondestructive techniques are preferred.…”

This research applies a novel combination of optical microscopy and SEM-EDX analysis to characterise the morphology and surface composition of environmental 'hot particles'. These widely available techniques offer a means to help identify the source and origin of particles, the way in 15 which they have been deposited, and the potential for their movement and redistribution. AbstractRadioactive 'hot particles' that occur in the environment present specific challenges for health and environmental regulators as often their small size makes them difficult to detect, and they are easily 20 dispersed and accidentally ingested or inhaled by members of the public. This study of nine hot particles recovered from the beach at Dalgety Bay, UK, uses a combination of gamma spectrometry, imaging microscopy and SEM-EDX in order to characterise their morphology and surface composition, thereby helping to identify their origin and source characteristics. The nine particles analysed showed great heterogeneity in their activities, physical form and elemental composition. 25The particle activities were dominated by 226 Ra and its daughters. Three distinct grouping of particles were identified based on their morphology (artefact, glassy and 'metal-rich'), whilst four distinct groupings (artefact, glassy, angular and porphyric, rounded and highly porous) were identified based on morphology and surface properties as seen in the SEM. Whilst the 'artefact' particles were little altered, the other particles showed evidence of incineration. All particles were in a size and / or 30 2 shape class vulnerable to wind-or water-mediated transport. No correlations were found between morphology and chemical composition. SEM-EDX analysis revealed C, Si, Zn, Fe, Ca are common in the particles together with Ba, Ni, Pb, Cu, Mn and Ti. This is interpreted as the particles being derived from radium containing luminescent paint containing a Zn/S phosphor, a hydrocarbon base and other fillers and additives. Evidence of copper and steel alloys were also present in some 35 particles, whilst one consisted of a hydrocarbon based 'capsule'. The combination of techniques employed here has enabled interpretation of the origins of the radioactive particles and given insights into the potential movement of particles within the local environment.
