Abstract: Iron-55 is a neutron-induced radionuclide produced in large
quantities from ferrous materials in the immediate vicinity of a
nuclear detonation. 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.;
