dc.description.abstractEnvironmental impact assessments conducted for Australian mine sites involving naturally occurring radioactive material require an assessment of radiation doses to wildlife. Whole-organism concentration ratios (CRwo) are pivotal in these assessments and previous reviews have identified a need for a more complete and consolidated database of Australian-specific CRwo that could be used. Concern had also been expressed by some stakeholders in Australia about the suitability of the default CRwo values provided in standard biota dose models (e.g., ERICA Tool, RESRAD-BIOTA, ICRP framework) for Australian wildlife and environmental conditions. In order to address these concerns and support the implementation of best-practice standards in environmental radiological assessment, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), with support from the Department of Resources, Energy and Tourism (RET), undertook an evaluation of existing data relating to wildlife inhabiting Australian uranium mining environments. CRwo values were calculated using data from a range of original sources. These included scientific journal publications, technical reports from Australian government organisations, site-specific data from mining operators and data from baseline environmental surveys undertaken during the 1970's and 1980's. The Australian data previously included in the international Wildlife Transfer Database (WTD, www.wildlifetransferdatabase.org) were also reviewed and updated. This paper discusses the data analysis process and associated uncertainties. CRwo values are reported for uranium, thorium, radium-226, lead-210 and polonium-210 for a range of endemic and introduced wildlife, with a focus on plants and animals from both terrestrial and freshwater environments where uranium mining has been proposed or undertaken. This has resulted in the calculation of more than 500 CRwo values for inclusion in the database. Australian-specific CRwo values will be compared to general values reported in the WTD including examples of specific wildlife groups or unique environmental conditions that are outside the range of the CRwo values in the WTD. Recommendations regarding biota types and environmental conditions for which data are most lacking will also be discussed. ©2008 IUR - International Union of Radioecologyen_AU
