one Considering the atoll as a whole, and the three successive test series, the evidence from Figure 2 suggests that the 1956 serles contributed not more than 1/100 as much radioactivity as the original 1294 faliout, and the 1958 series, not more than L/estn as much as tie 1956 series. it} lsu concluded that tie nerthern part of Rongelap Atoll _reseived a heavier taullout from the March 1, 1954 detonation at Brrind taw cia che southern pert. In contrast, the relatively Slicat Callout from laser deton tions affected the soukthern rom thin the northern partis of the atoll, as is evidenced by fae hi sier levels of radiozctivity at Rongelap Island than at Kearecle Island. “Ua:
