In addition to LLNL has created a unique data bank, pulling together radiological data from all the various organizations which have done environmental sampling and dose work since 1954. Recently, DOE, through LLNL, integrated its program at Bikini Atoll with the congressionally-created conducting Bikini Atoll Rehabilitation Committee (BARC) and are remedial experiments which will enable informed decisions on how Bikini can best and most cost-effectively be resettled. There are three specific tasks identified in the compact which are related to dose assessments for DOE. and environmental research and monitoring which LLNL performs These are: A review of the Rongelap dose assessments and restoration of rehabili- tability of Rongelap if required. A dose assessment of Enjebi Island at Enewetak Atoll and recommendations on resettlement. Rehabilitation of Bikini Atoll (Bikini and Eneu Islands).
