1. Delayed neutrons are associated with the beta decay of the fission products . 2. Fission of the nuclear fuel in any reactor produces neutron-absorbing fission products . 3. See fission product yield for a comparison with other radioactive fission products. 4. The bulk of the fission product elements remained stable in the salt. 5. See fission product yield for a comparison with other radioactive fission products . 6. One of the important fission products is krypton-90, a radioactive noble gas. 7. See fission products and the external links for more details concerning radionuclides. 8. The cause of the embrittlement was tellurium-a fission product generated in the fuel. 9. Iodine-131 is another important gamma-emitting radionuclide produced as a fission product . 10. Pulsed columns then purify the plutonium, removing the troublesome fission products that remain.
