ABSTRACT The task has been to determine whether or not DOE's 1982 Report proved that Rongelap Island is safe for habitation. The island was contaminated in 1954 during the testing of nuclear weapons. It should be borne in mind that the dosage under discussion is current dosage, e.g., from 1990 to 2020, and not that from exposure in 1954. The current [population]* dosage over a 30-year period is a matter of 3 rem [or less}, whereas [that of 1954] was one of 190 rem in 2 days. The evidence used by DOE plus additional and more recent information have been reviewed. a Rongelap Island is safe for habitation by adults provided that the diet is equivalent to that formerly used. I do not believe that such a diet would present any difficulty. {It comprises local plus imported foods.) Measuremnent of plutonium excretion in the urine of Rongelap residents (1981) [by the Brookhaven National Laboratory] shows very great variation, [and it is quite inconsistent with studies by the Lawrence Livermore National Laboratory]. The matter is a potential cause of concern and should be studied {now} although it is not associated with overexposure. The dose to infants and small children is another potential cause of concern. Preliminary findings from a diet survey indicate, however, that the dosage is not excessive. This study should be continued. The whole-body counting for cesium should be resumed to establish a base line for later work at the time of resettlement. In the course of planning for [Atoll] resettlement, the fact that Rongelap Island appears safe for resettlement now should not be lost Sight of. Planning for resettlement [of the Atoll} should consider the possible use of potassium-salt treatment of the soil and soil removal as studied at Bikini. To obtain a brief summary of the key facts of dosage and the nore general, but important human factors that will affect decision-naking, the reader is referred to Sectyon 4.5 (Dose Summary) and to Section 5 (Discussion and Recommendations.) {The standards of safety in this Report -- as is to be expected -are those employed currently in the U.S., where the radiation protection guide for the general population is 5 rem in 30 years (.17 ren/yr), whole body exposure (technically, the committed effective dose equivalent). The protective action guide is 0.2 rem/yr to the bone marrow (committed dose equivalent). These matters are discussed in Note 5.] *Bracketed paterial has been added to this edition for clarification or correction. 3 2000b11
