'Cerium radionuclides contribute a large portion of the
fission-produced materials occurring in sea, water soon after the
detonation of a bomb. This was shown by a radiochemical analysis on
sea water collected near Bikini Atoll in June, 1954, following the
hydrogen bomb tests which occurred during the period March to May,
1954. Also, on land the greatest amount of radioactivity from
fallout is contributed by the rare earth elements. The average of
two complete soil assays, determined two years after the Marshall
Islands were contaminated by fallout from the March 1, 1954,
nuclear detonation of Operation Castle, gave 84 % rare earths.'
