at Bikini and Eneu Islands in an effort to establish trends in the transport and loss of radionuclides at these locations. II. Concept of Operations The April 1976 Radiological Survey will include sampling of terrestrial biota and soil, and external radiation measurements at Bikini, Eneu, Nan, Boknegen, and Bokata Islands. In addition, catchment water and/or well water will be sampled from existing sources on Bikini and Eneu Islands, Personnel and cargo will assemble at Kwajalein and continue to Bikini Atoll via a Kwajalein Missile Range C-54 charter flight to Eneu. At this point the radiological survey team will rendezvous with the R.V. Liktanur and with returning members of the BNL Medical Survey Team. The R. V. Liktanur will provide the base of operations for the radiological survey and will transport survey personnel and cargo to Kwajalein when the survey is completed. Samples will be shipped via military aircraft and commercial air freight from Kwajalein to BNL and LRE for analysis. III. Organization and Responsibilities The management of all survey operations will be the responsibility of the BNL Field Survey Leader. representatives of: The survey team is expected to include a) Brookhaven National Laboratory (BNL); b) University of Washington (LRE); c) Bureau of Radiological Health (USDHEW; BRH); d) State University of New York, Stony Brook (SUSB).
