Advisor

Four of these badges apparently were actually
worn by four of the twenty-five men from the 6th Weather Squadron there.
Two others were placed on exposed positions on the island.

The six remaining badges were stored in a refrigerator

An assignment of exposure to personnel was made by the TG 7.4 Technical Advisor and was recorded by the NCO in charge of dosimetry and decon~
tamination in the TG 7.4 Nuclear Applications Section.
This assignment
has been filed along with the 5x8 cards on which Reference 13 is based and
can be found in the microfilm file
(Reference 87).
Unfortunately, in this assignment of exposure, two errors were made
that in turn have been picked up in Reference 13.
The first error was
that 15 of the 25 Air Force personnel established as being on Rongerik
were not assigned an exposure.
The second error was the assignment of an
exposure to a Surname not otherwise established as belonging to any man
known to have been on Rongerik at the time.
The person with this surname,
not accompanied by given name, rank, or Serial number, or other identification, was recorded in Reference 13 as having received 40 R.
ment of the other men's exposures is straightforward.

The three Army men
of the 9710th TSU were assigned the exposures from the "6.6 tent" pole
badge
(98 R), and the ten Air Force men were assigned exposures between
40 R and 52 R, based perhaps on a knowledge of their activities.
PATAPSCO CREW.
The contribution of the crew of the Patapsco to the
collective exposure is based on a recent estimate that considered the
natural washdown provided by documented rain and the weather-deck versus
below-deck exposure
(Reference 96).
