(4) b. c. d. Information was omitted that pertained specifically to Enewetak and Bikini, although reference to the first two booklets was included. (5) Information was added describing how the survey was performed by scientists from the Lawrence Livermore National Laboratory. (6) ;:~l:~:gical information was added for al 1 the northern Marshal 1 . Based on experience with the first two books (including questions and issues raised. by discussions with the people from Enewetak and Bikini, their attorneys, and representatives), changes were made to improve Also, information communication of information about radiation. specific to Enewetak and Bikini was omitted, and information specific to all the northern Marshall Islands was added. In the Enewetak and Bikini books, specific information was given for plutonium and americium because the tests of nuclear weapons on these atolls resulted in local deposition of sufficient quantities of these radionuclides to cause concern that they could contribute significantly to radiation doses at those atolls. This was not the case on Rongelap Island. According to the survey results published in the Lawrence Livermore National Laboratory Report, UCRL-52853 Pt. 4, September 30, 1982, the people living on Rongelap Island might receive an integrated bone marrow dose of 3.3 rem, of which only 0.00051 rem was from The ingestion and 0.0078 rem was from inhalation of plutonium. contribution of americium to the 3.3 rem was 0.0012 rem and 0.0033 rem from ingestion and inhalation, respectively. These radionuclides contribute, therefore, about 0.4% of the total bone marrow dose. The dose values published in the DOE-1982 booklet included these very small The profiles for plutonium contributions from plutonium and americium. and americium were not included because of their relatively small contributions to total dose in comparison with their contributions on Enewetak and Bikini and in comparison with the important contributions to the dose on Rongelap from cesium and strontium. I believe the clarity of the booklet was improved by not including irrelevant information about plutonium and americium. Response to Question 4 a. b. c. d. I believe the radiation doses in the DOE-1982 booklet included contributions from all the atomic bomb tests, because the Lawrence Livermore National Laboratory survey team measured the total radionuclide contents of soils and foods. The DOE-1982 booklet did not consider radiation and related effects only from the March 1, 1954 “Bravo” test. To the best of my knowledge, the DOE-1982 booklet considered all of the bomb tests, including “Bravo.” The baseline used for defining radiation effects was the dose information reported in Lawrence Livermore National Laboratory Report, UCRL-52853 Pt. 4, September 30, 1982. 3
