C. Fission: may create radioactive nuclei, may undergo a chain reaction Fusion: energy source for stars Fission and fusion: large amount of energy produced
Neptunium-239 has a half-life of about 2.4 days and decays into plutonium-239, also through beta decay. Although it does not occur naturally, uranium-233 is also a fissionable material that can be used as a fuel in nuclear reactors.To produce uranium-233, atoms of thorium -232 are exposed to neutrons. Thorium-233 forms when thorium-232 absorbs a neutron.eptunium-239 has a half-life of about 2.4 days and decays into plutonium-239, also through beta decay.
