The half-life of plutonium-239 is 24,360 years. If 10 g of plutonium is released into the atmosphere by a nuclear accident, how many years will it take for 75% of the isotope to decay? It will take years for 75% of the isotope to decay. (Do not round until the final answer. Then round to the nearest year as needed.)
