$$^{129}$$I/$$^{127}$$I ratios in surface waters of the English Lake District

Atarashi-Andoh, Mariko  ; Schnabel, C.*; Cook, G.*; MacKenzie, A. B.*; Dougans, A.*; Ellam, R. M.*; Freeman, S.*; Maden, C.*; Olive, V.*; Synal, H.-A.*; Xu, S.*

Accelerator Mass Spectrometry (AMS) was used to measure $$^{129}$$I/$$^{127}$$I ratios in surface sea, lake and river water samples collected in 2004 and 2005 from the English Lake District and from South west Scotland, areas which are in relatively close proximity to the Sellafield nuclear fuel reprocessing plant in north west England. The $$^{129}$$I/$$^{127}$$I ratios in surface water collected from the shore of the Irish Sea were in the range 2.8$$times$$10$$^{-6}$$ to 8.2$$times$$10$$^{-6}$$. These ratios are one order of magnitude higher than that of seawater collected from the Irish Sea in 1992, correlating with the increase in $$^{129}$$I content of the Sellafield liquid effluent discharge over the last decade. The $$^{129}$$I/$$^{127}$$I ratios in lakes in the Lake District were in the range 0.7$$times$$10$$^{-6}$$ to 6.4$$times$$10$$^{-6}$$ and decreased exponentially as a function of distance from Sellafield.
