The relative significance of past and current discharges from S`field as sources of present human radiation exposure - AE0117

Description
R&D Summary Objectives:- To differentiate the relative importance of past (historical) and current authorised discharges of radionuclides to the sea from Sellafield as sources of present human radiation exposure, and to quantify the separate contributions in accordance with the new philosophy of dose constraint as recommended by the ICRP. Key Customer Purpose:- To enable MAFF to review, on the basis of the best scientific information, its policies under RSA 1960 on the authorisation of current discharges to sea from Sellafield, and to provide a continuing assessment of the hazard arising from past discharges for which intervention measures might be appropriate.
Objective
This project will involve work to predict the future concentrations in water and on sediment particles of long-lived radionuclides (e.g. plutonium and americium) from both current and historical discharges in the Irish Sea. The capabilities and shortcomings of existing predictive tools and models will be evaluated in the context of modelling both current and historical discharge scenarios. As required, existing models will be developed by the inclusion and quantification of additional environmental processes and predictions will be validated with observed radionuclide distributions. Consequently, it will be possible to justify any necessary actions of remedial measures and revision of discharge authorisations.
