摘要

The association of Co-60 and Cs-137 to different particle size and density fractions of sediments from Tvaeren Bay, northern Baltic proper, has been investigated. An attempt to use density gradient centrifugation for the fractionation indicated that this method may be useful for sediment studies if further developed. Enrichment of Co-60 was observed in the high density (mineral) fraction as well as in particles in the size range 2-60 mu m. Cs-137 was enriched in the high density fraction as well as in some of the light (organic) fractions. In the size fractionated samples a large enrichment was found in the smallest (<= 2 mu m) fraction. Also in the other fractions up to 60 mu m enrichment occurred. (Atomindex citation 16:057739)
