Field test of the IMEEDS radionuclide sampling system
This report describes the function and performance of a seawater sampling system. The purpose of the sampling system is to process water and isolate, or concentrate man-made radionuclides present in the marine environment. Many of these isotopes are present in natural waters at extremely low levels, if at all. Also, biogeochemical processes in the environment sequester elements so that any given analyte may be in a compound, molecular, or ionic state, and associated with solid, colloidal and dissolved phases. The distribution of radioisotopes in natural waters is controlled by chemical speciation, pH, temperature, redox conditions, complex formation, adsorption and desorption, salinity, conductivity, and hydrolytic colloid formation (Harvey et al., 1990; von Gunten and Benes, 1995). Therefore, the goal of this work is to develop a sampler that is capable of isolating suites of radionuclides as they are found in the environment.
