8. A fresh spent nuclear fuel was removed from a reactor core and placed into a spent fuel pool. One of the activation products in the nuclear fuel was Cobalt (Co-60). After 8 year of storage in the pools, the activity of the Co-60 was reduce to 0.5x105 Ci. Please determines: i)The initial activity of the Co-60 at the day when the spent nuclear fuel was stored in the pool. [Given that half-life, t1/2 of the Co-60 is 5.26 yr]...
