Fallout patterns and RENDon the Wmanuclear tests
are very limited.
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.

Only on RONGELAP, BIKINI
