dc.description.abstractBetween 1960 and 1968 low-level radioactive waste was buried in a series of shallow trenches near theLucas Heights facility, south of Sydney, Australia. Groundwater monitoring carried out since the mid1970s indicates that with the exception of tritium, no radioactivity above typical background levels hasbeen detected outside the immediate vicinity of the trenches. The maximum tritium level detected ingroundwater was 390 kBq/L and the median value was 5400 Bq/L, decay corrected to the time ofdisposal. Since 1968, a plume of tritiated water has migrated from the disposal trenches and extends atleast 100 m from the source area. Tritium in rainfall is negligible, however leachate from an adjacentlandfill represents a significant additional tritium source. Study data indicate variation in concentrationlevels and plume distribution in response to wet and dry climatic periods and have been used todetermine pathways for tritium migration through the subsurface.Crown Copyright © 2010 Published by Elsevier Ltden_AU
