A survey was made two years post-detonation to determine the persistence
and fate of radioactive material in the biological systems and in the
physical enviromnent of those Marshall Islands contaminated by fall-out
from the March 1,
1954,
thermonuclear weapon detonation.
Specimens
of land
and marine animals, birds, vegetation, soil, and water were collected for
analysis. Radioassays for gross beta and gamma activity were conducted, and
in addition radiochemical determinations of individual fission products and
induced activities were made. Data are tabulated. An evaluatlon is made of
the potential hazard from the ingestion of contaminated materials. (C.H.)

the Marshall Islands, and Ponape. These tests shows that the Bikini and
Rongelap populations were severely damaged genetically by the direct
radiations and fallout from the thermonuclear device exploded on March 1,
1954. The Rongerik atoll populations had recovered from fallout by August
in
1955 -- a period roughly equivalent to 26 generations. The populations
collected at Rongelap and Bikini had not recovered then, but the Rongelap
population had recovered by 1956, in 40 or more generations. Because of the
heavier irradiation on Bikini--including effects of the weapons tests in
1956--this population was still slightly below other Pacific Island
populations even in 1957. The general relations and comparisons between
these isolated island populations and other Drosophila-populations are
