Radioactive decay. Iodine-131 has a decay rate of 9.6% per day. The rate of change of an amount N of iodine-131 is given by where t is the number of days since the decay began. a) Let represent the amount of iodine-131 present at Find the exponential function that models the situation. b) Suppose that 500 g of iodine-131 is present at How much will remain after 4 days? c) After how many days will half of the 500 g of iodine-131 remain? t = 0. t = 0. N0 dN dt = -0.096 N,
