Radioactive plutonium-239 (t½ = 2.44 x 105 yr) is used in nuclear reactors and atomic bombs. If there are 4.4 x 102 g of the isotope in a small atomic bomb, how long will it take (in yr) for the substance to decay to 1.0 x 102 g, too small an amount for an effective bomb? This radioactive decay follows first order kinetics.
