-12northwestern part of Rongelap received at least 3,300 roentgens during the first 96 hours of fallout from the cloud, while across the atoll amounts as low as 170 roentgens we:re measured. The people of Rongelap, who were living in the south, are estimated to have received a dose of "up to 175 roentgens before they were evacuated." S. Glasstone, ed., op cit. 463. This was the estimated whole body exposure to gamma radiation. At Utirik the whole body gamma exposure was estimated at 14 rads. R.A. Conard, A Twentv-Year Review of Medical Findings in a Marshallese Population Accidentally Exposed to Radioactive Fallout 11 (Brookhaven National Laboratory 1975) (hereinafter referred to as “Brookhaven Report"). At. Rongelap, within 4 to 6 hours after the Bravo explosion, the radioactive ash began to reach the ground. To these people of the tropics, the strange, snowlike material fluttering down from the sky gave no hint of its true nature. Children played in it as it collected in large amounts on the ground. The curious touched it and tasted it in an effort to understand this heretofore unknown phenomenon. At Ailinginae and Rongerik, 4 to 8 hours after the explosion, radioactive fallout of a mistlike quality was observed by the people. The estimated dose of gamma radiation received by the people at these atolls was between 69 and 79 rads. -
