Passage: Initially, gamma radiation from the fission products of an equivalent size fission-fusion-fission bomb are much more intense than Co-60: 15,000 times more intense at 1 hour; 35 times more intense at 1 week; 5 times more intense at 1 month; and about equal at 6 months. Thereafter fission drops off rapidly so that Co-60 fallout is 8 times more intense than fission at 1 year and 150 times more intense at 5 years. The very long-lived isotopes produced by fission would overtake the 60Co again after about 75 years.The triple "taiga" nuclear salvo test, as part of the preliminary March 1971 Pechora–Kama Canal project, produced a small amount of fission products and therefore a comparatively large amount of case material activated products are responsible for most of the residual activity at the site today, namely Co-60. With this fusion generated neutron activation product being responsible for about half of the gamma dose now(2011) at the test site, albeit with that dose being too small to cause deleterious effects, normal green vegetation exists all around the lake that was formed.

Question: How intense is the fission emitted from gamma radiation Co-60?
8 times more intense than fission at 1 year and 150 times more intense at 5 years
