On the basis of this investigation, the following islands are
extremely unlikely to have received fallout from the Bikini or Enewetak
tests at levels higher than the background exposure of 200 mrem/year:
Wotto
Ujae
Lae
Lib
Majuro
Namorik
Kusaie
polka
otje
Erikub
*Haloelap
Arno
Kiti
Kwajalein
.
Aur
Namu
Jabwot
Ailinglanelep
Mi7i
Narik
daluit
Ebon
and any other islands circumscribed by the above.
The following islands may have received some falldbut from
nuclear tests.
It is unlikely that the intensities would have resulted
jn an exposure of more than 2 rem the first year; subsequent annual
exposures would have been less than background:
Jemo
oS
Ailuk
Mejit
The following islands did receive fallout with intensities
ranging from 1 to 2000 R/hr at l hr.
They are listed in estimated
order of decreasing residual activity:
Rongelap
Taongi (based on cloud drift only - no survey data available)
Rongerik
Ailinginae
Bikar
Utirik
Taka
TT.
CONCLUSIONS
The above estimates, even when corrected for soil migration,
can only be considered preliminary; they are very likely to be upper
bounds. Wote that only Cs!?” has been considered. The addition of
sr20 (a beta-emitter) and £09 (which results from weapon debris activation) are necessary in completing the estimates of the total activity
present.
