(Ne 73). Eviscerated fish samples are described (Ne 73, Nev 75) as the entire fish with the gonads, gills and G.I. tract removed. The dry viscera Samples from these reef fish contained an average of 430 pCi/kg of 2392405, Using equations given by Wilson, et al., (Wi 75) and Robison, etal., (Ro 78), and a dietary fish intake of 600 wet gm/day, the dose rate fro m 239240, ingestion at these concentrations is 10-25% of the 3 mrad/yr guideline proposed by EPA (Ep 77) for annual total transuranic dose to bone. A percentage this high, resulting from a single transuranic in one ingestion pathway is sufficient reason to warrent a re-examination of the concentrations of plutonium at Kwajalein and to resolve some of the questions raised from the previous report Plutonium in water, (No 76). Concentrations of fish and sediment in recently collected samples from Kwajalein and north equatorial surface waters are discussed and compared to previously reported data. ES RCHIV DOE A
