Abstract
/sup 137/Cs, sup(239,240)Pu, /sup 90/Sr and /sup 238/Pu were determined. The results showed that /sup 137/Cs, sup(239,240)Pu and /sup 238/Pu were found at low concentrations (max 0.142 pCi/g /sup 239/Pu) in the skin, viscera, and G.I.T. contents for some of the fish collected. The edible muscle for the fish generally contained levels at or below the sensitivity limits of 0.005 pCi/g dry sup(239,240)Pu. The sediments contained maximum concentration levels of 0.14 pCi/g (dry) /sup 137/Cs in the surface section of the box cores. The sup(239,240)Pu concentrations were measured as deep as 16 cm in certain sediment cores indicating rapid vertical transport, possibly by burrowing organisms. The /sup 210/Pb concentration profile also showed high effective sedimentation rates of 1-3 mm/yr and possible mixing of the upper sediments. The submersible cores taken near the canisters indicated loss of the surface layers during collection but contain 2-20 times greater integrated deposition than the expected fallout levels of 1.8 +- 0.6 mCi/km/sup 2/.
