ABSTRACT
A field sampling program was conducted on Cattaraugus and Buttermilk
Creeks, New York during September 1978 to investigate the transport of radio-
nuclides in surface waters as part of a continuing program to provide data for
application and verification of Pacific Northwest Laboratory's (PNL) sediment
and radionuclide transport model, SERATRA. Suspended sediment, bea sediment,
and water samples were collected during low flow conditions over a 45 mile
reach of stream channel. Radiological analysis of these samples included
primarily gamma ray emitters; however, six alpha and beta-emitting radio-
nuclides were analyzed using radiochemical methods. The Nuclear Fuel Ser-
vices facilities are a possible source of two gamma-emitting radionuclides:
1) Cesium-134, and 2) Cesium-137. The principal beta-emitter found was
Strontium-90. Elevated levels of both CesiumKl37 and Strontium-90 were found
at the sampling stations immediately downstream of the facilities. Based on
cownstream trends of activity levels of other radionuclides, the Nuclear Field
Services facilities may also be a possible source of Plutonium-238 and 239,240,
Americium-241, Curium-244, and Tritium. This field sampling effort is the
second of a three phase program to collect hydrologic and radiologic data at
three different flow conditions.
