Test
Different quantities of the radioactive fission and activation
products, generated during the explosions, were deposited on the lagoon and on
the islands of the atoll.
,
The U.S. moratorium on testing began on October 31, 1958, and marked the
end of all nuclear testing at the atoll.
However, even today quantities of
long-lived fission products, such as 1}37cs, 90sr, 155ey, and 'l3mcqg;
activation products, such as 5°Ffe, 60¢Co; and 20781; and transuranium
