239240Pu, 241Am, and 243244Cm in a core from the Saguenay Fjord, Quebec
Description
To assess the stability of plutonium within sediments, a set of sediment core samples from the Saquenay Fjord, Quebec has been analyzed. This is a unique experimental area in that the sedimentation rate is high, the post-depositional mixing is low, and there is a clear stratographic record in the sediments. A comparison of the 239Pu distribution with those of 137Cs and 210Pb as well as with the known 239Pu input function has provided information about the changes in plutonium distribution which has occurred with time. In addition the data can be used to improve the estimate of the atmospheric input function for plutonium prior to the early 1960's. This is discussed
