Plutonium-239 Production, Properties, Half-Life, Decay, Uses
Web10 mei 2024 · After measuring the 239+240 Pu concentration by α-spectrometry analysis, Pu on the stainless steel disc was extracted by immersion in a mixture of HNO 3 and HF for a few minutes. The Pu isotopes in the extracted solution were further purified by anion-exchange chromatography. WebPlutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in […] sharon daughter
