Type Map ref. (Fig. 1) 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 9000557 3
