Na mbido, gamma radieshon sitere na fission ngwaahịa nke oke fission-fusion-fission bomb dị ike karịa Co-60: 15,000 ugboro ike na 1 awa; 35 ugboro ike na 1 izu; 5 ugboro ike na 1 ọnwa; na ihe dịka hà na 6 ọnwa. Mgbe nke ahụ gasịrị fission na-ada ngwa ngwa nke mere na Co-60 fallout bụ 8 ugboro ike karịa fission na 1 afọ na 150 ugboro ike na 5 afọ. Isotopes dị ogologo oge nke fission mepụtara ga-agafe 60Co ọzọ mgbe ihe dị ka afọ 75 gasịrị.
