The Utirikese and Rongelapese returned to their home atolls in June 1954
and in June 1957 respectively.
The earlier repatriation of Utirik Atoll wis
based on the low level of external radiation exposure measured after the jiitial
3 month observation period (March to June 1954).
The Utirik population was not
examined by a Brookhaven medical team until March, 1957, when 144 people re=
ceived comprehensive physical examinations.
Following the 1957, medical survey,
two men, removed from Utirik for medical reasons, were whole body counted at
Argonne National Laboratory and provided urine samples for radiochemical inal1
