However, hodographs are known for nearly all of the tests conducted in the Pacific. These hodographs and available fallout patterns have been QM studied to discern which events may have << on Pacific atolls. Those hodographs and fallout patterns which Gam quate have positive indications or suggest significant fallout on these atolls are indicated, as well as the source of such information. Due to the intensive fallout from the CASTLE BRAVO event on RONGELAP and UTIRIK atolls, some effort was made in the past to investigate the radioactive deposition on these and a few otner atoils in the fallout pattern. Scklmueccp Unfortunately, the utility of thes investigations is limited due to the, atolls atta’ ee ely visited, the neni treatment of the samples (gross gamma, gross beta, and other crude evaluations), and age of the survey.
