An accident in 1986 at the Chernobyl nuculear plant in the Ukraine released a large amount of plutonium (Pu-239)into the atmosphere. The half-life of Pu-239 is about 24,110 years. Find the decay constant. Use the function N (t) = N 0 e -kt to find what remains of an intial 20 grams of Pu-239 after 5000 years. How long will it take for these 20 grams to decay to 1 gram?
