Bikini Atoll Lagoon is labeled at the present time with /sup 55/Fe at concentrations which are greater than for any of the remaining bomb-produced radionuclides; the concentrations found in the water are 120 to 680 pCi/m/sup 3/ and are estimated to be partitioned into 45 percent particulate (>0.3 ..mu..m), 45 percent colloidal and 10 percent soluble. The particulate and soluble fractions were determined by use of a Battelle Large Volume Water Sampler. The sediments in the lagoon and craters appear to be the sources of /sup 55/Fe and other radionuclides in the lagoon water. In spite of a 70-fold or greater decrease in radioactivity by decay since the last nuclear detonations at Bikini in 1958, some sediment contain concentrations of /sup 55/Fe as great as 300 pCi/g, dry weight.; Subject Categories: 520300* Materials Monitoring & INIS Subject Categories: 10/5/980 -- Environment, Transport B32* -- -- Water (Item 680 from file: 20040178 Major Descriptors: *BIKINI -- CONTAMINATION; *BIKINI -- RADIATION MONITORING; *IRON 55 -- RADIATION MONITORING; *IRON 55 -RADIOECOLOGICAL CONCENTRATION; *LAKES -- CONTAMINATION; *LAKES -RADIATION MONITORING; *SEDIMENTS ~- CONTAMINATION; *SEDIMENTS -RADIATION MONITORING Descriptors: CHEMICAL STATE; NUCLEAR EXPLOSIONS Broader Terms: BETA DECAY RADIOISOTOPES; ECOLOGICAL CONCENTRATION; ELECTRON CAPTURE RADIOISOTOPES; EVEN-ODD NUCLEI; EXPLOSIONS; INTERMEDIATE MASS NUCLEI; IRON ISOTOPES; ISLANDS; ISOTOPES; MARSHALL ISLANDS; MONITORING; NUCLEI; RADIOISOTOPES; SURFACE WATERS; YEARS LIVING RADIOISOTOPES Aquatic -- Radioactive (1989) 103) 00219136 INS-77-006644; ERA-02-027402; EDB-77-056944 Author(s): Nevissi, Title: Efficiency of a large volume water sampler for some radionuclides in salt and fresh water Affiliation: Univ.
