AVAILABLE FILM BADGE DATA
Film badge data pertaining to the radiation exposure on Rongerik are reported in

several references; however, the readings require interpretation. Because the allotted
badges were not worn continuously by each individual, the data do not necessarily
reflect the doses accrued by the servicemen.

Moreover, there are inconsistencies

among the references regarding the assignation of badges and in some of the reported
readings.

Either twelve (Reference 9) or fourteen (Reference 3) film badges were received
at the Rongerik weather station on 19 February 1954.

One of these (#314) was

distributed to the Army group. It was positioned seven feet above the floor of a tent
in the Army area and was not worn.

Two badges (#310/311) were assigned to the

radio-weather station and were worn by a member of each shift (CN 408/CN 416) until,
approximately 1130 hours, 2 March.

One badge (#312) was to be worn in the housing’

area by one of the Air Force personnel (CN 411) and another badge (#313), was worn
by the NCOIC of the camp (CN 419). One other badge (#315) was placed on the side of
a building in the housing area.

This one was located shoulder high and moved

occasionally each day to avoid direct sunlight. The remaining six badges (#309, #316#320) were placed in a refrigerator in the mess hali. According to Reference 3, there
were eight film badges placed in the refrigerator, but the reference does not cite
badge numbers as does Reference 9.
Of the six badges that were issued, five (all but #313) were collected at 1130
hours, 2 March, and placed in a manila envelope and set on a table in the mess hall.

The film badges that had been in the refrigerator remained there until 1700, at which
time they too were placed in the manila envelope in preparation for the final
evacuation.

CN 419 continued to wear badge #313 until he arrived at Kwajalein at

1900, 2 March 1954.
The first written report of the film badge doses accrued on Rongerik came in
Dispatch No. 240 431A from CTG 7.1, Enewetak and COMNAVSTA, Kwajalein,
received 25 April 1954, which stated (documents of the period reported doses in r

(i.e., R), not the modern rem):
