    Dangerous fission fragments ....

    krypton-82 ........ stable isotope ... no danger

    xenon-129 ........ stable isotope ... no danger

    strontium-90 ..... produced during U-235 fission. It has a half-life of almost 30 years and emits beta(-) particles as it decays into Y-90 which has a half-life of less than 3 days. Y-90 decays by beta emission to stable zirconium-90. It is the daughter isotope, Y-90, which is more dangerous than Sr-90 itself because of the greater energy of the beta particle. Sr-90 is more problematic in another way, since it behaves chemically like calcium (both are alkaline earth metals), and is taken up by bones should the Sr-90 be ingested.

    barium-138...........stable isotope ... no danger
