On Rongerik, the exposed individuals recognized the nature of the
fallout, put on protective clothing, and took advantage of the partial ~
gamma shielding afforded by Butler-type buildings in the area, staying _
indoors as fer as possible,
The radiation dose rate encountered by an-
individual on this island tms depended on his whereabouts and probab-~
ly varied by a factor of two between maximum and minimum values in
different areas at a given time, The estimation of dose received by
any one individual of the Rongerik group was thus subject to considerable uncertainty, since no cauplete record of movements was kept.
