On Rongerik, the exposed individuals recognized the nature of the

fallout, put on protective clothing, and tack advantage of the partial
gauma shielding afforded by Butler-type tuildings in the area, staying
indoors as far as possible, The radiation dose rate encountered by an
individual on this island thus depended on his whereabouts and probab~
ly varied by a factor of two between maximum and miniaum values in
different areas at a given tine, The estimation of dose received by

any one individual of the Rongerik group was thus subject to consider=
able uncertainty, since no canplete record of movements was kept,
