This report describes FY-1979 analysis results on flow, sediment and radionuclide data collected in Cattaraugus, Buttermilk and Franks Creek, New York. The objective of the study is to investigate the radionuclide transport in these streams as a part of a continuing program to provide data required for application and verification of the Sediment and Radionuclide Transport Model (SERATRA). Radiological analyses were performed on sand, silt and clay size fractions of suspended and bed sediment, as well as for dissolved radionuclides. These include gamma-ray emitters plus {sup 90}Sr, {sup 238}Pu, {sup 239 - 240}Pu, {sup 241}Am, {sup 244}Cm and {sup 3}H. Among radionuclides analyzed to date, a principal radionuclide found in the study area is {sup 137}Cs. Distributions of {sup 137}Cs associated with suspended and bed sediments have sharp peaks at the mouth of the Franks Creek, revealing the contribution of {sup 137}Cs from the NFS site. Concentration of {sup 137}Cs associated with a clay size fraction of suspended and bed sediments at the mouth of Franks Creek were 32.5 {+-} 1.5 and 134.0 {+-} 0.90 pCi/g, respectively. Cesium-134 and cobalt-60 associated with the bed sediment also have higher peaks at the mouth of Franks Creek. However, dissolved and particulate concentrations of other radionuclides analyzed under this study were generally very low and there is no clear evidence more » to indicate that these radionculides detected in this study area originated from the Nuclear Fuel Service site. « less |
