SRS produced nearly all the plutonium-238 for every U.S. mission that has relied on these batteries. Together, the technologies represent a peaceful application of radioactive materials. Acknowledgements WebPlutonium has no known biological role. It is extremely toxic due to its radioactivity. Natural abundance The greatest source of plutonium is the irradiation of uranium in nuclear reactors. This produces the isotope plutonium-239, which has a half-life of 24,400 years. Plutonium metal is made by reducing plutonium tetrafluoride with calcium.
