gram similar to the one given on Rongelap in 1977. Lessard and Miltenberger proceeded to Rongelap to collect additional urine and environmental samples and conducted an external exposure study at the northern islands of Rongelap Atoll. The wind-powered electric generator had malfunctioned here too. An attempt to repair the wind-vowered generator also was made, however, no long term successful operation of the system could be achieved. Greenhouse and Xuehner of BNLSEP joined the field team at Bikini. siding on Bikini, 99 were whole-body counted. Of the 143 persons re- Additionally, urine samples and environmentai soil, air and vegetation samples were collected. locally prepared indigenous Samples of food items such as jekaro (coconut sap), jekami (coconut syrup) and powdered taro flour (a starchy tuber based flour) were obtained. The wind-powered generator on Bikini was not working nor could it be repaired. The Bikinians were made aware of the fact that their prior body burdens had tncereased to new levels and many of them knew they exceeded the internationally accepted annual guidelines for dose-equivalent commitment. In June 1978, the RUDR program contracted the meteorological group at LLL, headed up Gudiksen, to provide a computer simulation of the dispersion, transport and deposition of fallout BRAVO. from the 1954 atmospheric nuclear test, Also, a contract to provide neutron activation analyses of environ- mental samples for I-127 and I-129 resulting from the deposition of fallout on Rongelap and Utirik Atolls was given to the Radiological Sciences Department, Battelle-Pacific Northwest Laboratory (BPNL) under the guidance of Brauer and Ballou. Historic soil samples from Rongelap and Utirik Atolls were provided by Seymour, the director of UWLRE. In August, Sondhaus of UCCM was asked to collaborate on the dose reassessment project (RUDR).
