a ten ren figure would be an adequate planing factor for Strategic Air
Command pilot total exposure during HARDTACK.*/
Farly in March 1958, plans were made by the Nuclear Research Officer
to procure and issue film badges to all personnel of Task Group 7.4.
Con=
sequently, Group Regulation 160-1, published on 22 March, established the
procedures and provided information for determining and recording exposures
of personnel to ionising radiation.
To provide for the radiological safe—
ty of personnel participating in the test series, it was necessary to dé-
‘termine the accumlated exposure of each individual, a determination accomplished through the use of "flim tadges."
The film bedge, similar to
that used for REDJING, consisted of a small plastic encased piece of specelal photographic filmy and, when developed and analyzed, the film indicated
the amount of ionizing radiation to which it had been exposed. All persennel, therefore, received an initial issue before the first shot of the
HARDTACK series, and replacement issues were to be made, depending upon
the dities and length of tour in the proving ground of each indtyidual.
Establishment of Weather Islends.* Ry early August 1957, because of
certain Joint Task Force SEVEN survey and plaming actions, much thought
was already being given to the establishment of surface and rawinsdnde
statiens at Kusale, Kapingamarangi, Tarawa, Nauru, and Utirik, and/of sur-
face dnd pibal (pilot balloon) observation stations at Rongelap, Votho,
and Ujelang.

history of the Weather Keporting and Forecacting Zlesent, Trovisional far
FARDTACK, 1958.
