eraft FLDINGS” A ippecrentiy here are eleven nuclear tests which may have deposited radioactive materials in significant amounts greater than world wide fallout on several of the Pacific Atolls. These events and the atolls they may have contaminated are indicated in tabular form in Table 1. Additionally, the fallout pattern, if available, or several hodographs are indicated in Figures through sg for each contaminatingevent. XABEY For immediate reference, the habitation of the atolls under discussion is indicated, with yorulation figures and remarks, where applicable, in Table 2. It is pertinent to note that in addition to ENIWETOK, BIKINI, AILINGINAE, x SONGSLAP, RONGERIX, BIKAR, TAKA, SMM UTIRIK, and LIKIEP atolls, which have arct =. .922n looked at by others at some time in the past, several other atolls are In a wereee indicated: AILUK, JENO, KWAJALEIN, LAE, MEJIT, TAONGI, UJAE, UJELANG, WOTHO XXZ and WOTJE. Since the utility of the studies Gongon BIKAR, TAKA, LIKT=> and possibly AILINGINAS samt RONGERIK, and UTIRIK, is somewhat limited, these “4 may also added to theexceptions above. This would mean that, including the "source" atolls of ENIWETOK and BIKINI, & total of 19 atolls may have dean contaminated with ‘significant’ amounts of radioactive materials. Only on three, ENIAETOK, BIXINI and RONGEIAP, vossibly four if UTIRIK is included, is there any usefuletiforpantay/f radiological data. _ o suspicious ~~ | é Since actual fallout patterns are lacking for fost of the eentaminating~ “events, an attempt was made to weigh the potential of each event, in-euch -amanner as to make senge. Since the fallout pattern of the CASTLE BRAVO ‘est DOE ARCHIVES event is well known (actually there are three different fallout patterns cd CAS LC BCE available) this derosition potential was normalized to jthat-event. AQé& a treatment ie presented in Table 3. fris_ik The potential expressed here is really a factor, or multiplier, of the CASTL2 BRAVO fallout. It may be applied eimriv by taking the CASTLE BRAVO deposition at a distance from the GZ -ead- ys
