Environmental protection from ionising contaminants in the arctic


Traditionally, radiological protection has relied upon the tenet that if man inadequately protected from radiation, then the environment will also be protected. The belief has been perennially criticised and it is clear that society would benefit from a more rigorous protection system that explicitly includes the environment. The aim of this project will, thus, be to develop a framework for the protection of a pristine environment (Arctic) from radioactivity. This work will be achieved primarily through the development of models relating to the environmental transfer of radio nuclides, through the development of dosimtericmodels and through the compilation of information relating to dose effects relationships for reference Arctic biota. The result will be a complete methodology allowing the impact of actual or potential radio nuclide releases tithe Arctic to be assessed and numeric standards to be defined.
The project has been successful in developing a system for assessing the impact of exposure to ionising radiation on Arctic wild-life. The constructed system may also be used in the process of setting dose limits for Arctic ecosystems, and may currently be used to guide decision making. Deliverbale reports provide the detail of the underpinning science supporting the system. Extensive data-sets on radionuclide transfer to Arctic biota have been collated and new food-chain transfer models have been developed. Dosimteric model have been constructed for specific application to selected Arctic fauna and flora and a large database on dose-effecst for boreal and Arctic organism has been generated from an extensive review of Russian literature.
