Walney Offshore Windfarm Radiological Assessment of Disturbed Sediment During Construction

Walney Offshore Windfarm Radiological Assessment of Disturbed Sediment During Construction

Top Categories:

Sedimentology

Description

Following the completion of the Walney Offshore Windfarm (WOW) Environmental Statement (ES) a response from CEFAS recommended a desk-based assessment be performed to determine the risk to human health from the sediment that could be disturbed during the windfarm construction. To satisfy this response in April 2007 Westlake Scientific Consulting (WSC) has performed a radiological assessment relating to the sediment disturbance that may occur during the construction of WOW. In summary, Committed Effective Dose (CED) values were derived from generating average radionuclide activity concentrations in sediment of the Walney Offshore Windfarm region, calculating quantities of radionuclides released into the surrounding seawater and then the uptake into seafood species. The consumption rates of these seafood species were taken to be the same as those for the critical groups at Heysham and Sellafield.
