Abstract
In 1990, the National Oceanic and Atmospheric Administration`s National Status and Trends Program initiated a study of artificial radionuclides ({sup 241}Am, {sup 239+240}Pu, {sup 238}Pu, {sup 137}Cs, {sup 110}Ag, {sup 90}Sr, {sup 65}Zn, {sup 60}Co, and {sup 58}Co) in oysters and mussels collected along the coastal US. The results of this study show that activation products {sup 110}Ag, {sup 65}Zn, {sup 60}Co and {sup 58}Co are sometimes present close to nuclear facilities. In addition, based on a nonparametric Kruskal-Wallis statistical test, it appears that {sup 241}Am and {sup 137}Cs concentrations as well as {sup 241}Am/{sup 239+240}Pu and {sup 137}Cs/{sup 40}K activity ratios are highest along the West Coast of the US. For {sup 238}Pu, {sup 239+240}Pu, and {sup 90}Sr activities and the other ratios, the differences observed in the distribution of the radionuclides between the various coasts are not statistically significant. There is also a statistical difference between the values of the {sup 239+240}Pu/{sup 90}Sr ratio in oysters vs mussels collected along the East Coast and of the {sup 241}Am/{sup 239+240}Pu ratio between two species of mussels collected along the West Coast. Finally, when the NOAA results for {sup 241}Am, {sup 239+240}Pu, and {sup 137}Cs are compared with those of
